It should not behave like that. Can you please try after removing CauasesValidation attribute from button tag.

Have you tried with the following statement for ItemTemplate of Repeater control:

<asp:Image ID="Image1" ImageUrl='<%#Container.DataItem("Column_Name")%>' runat="server" />

Replace Column_Name with your database column name which contains the url to image.

Welcome. :)

Are you facing any other problem??

I think you need to modify the below statement
<input type="submit" önclick="xyZ(),abC(),deF(),open_win()">
to
<input type="button" önclick="return open_win();"/>

and in open_win() :
function open_win() {
if(xyZ() && abC() && deF())
window.open("hello.html","_blank","width=400");
else
alert("Register Again");
}

and modify all other function to:
function xyZ(){
if(...) // your validation goes here
{
return true;
}
else
{
return false;
}
}

similarly modify all other functions as above.

hope this will help. :)

Don't know why you are invoking xyZ(), abC(), deF() twice. one by onClick event and the other time you are invoking in open_win().

And one more thing are you sure you are returning true/false based on the success or unsuccessful execution of these functions?

Most welcome dear. Happy to help. :)

okay no problem. you can send me at me.chinmaya@gmail.com.

try commenting all the other javascript functions other than popup, then try..

Can you do one more thing.. Create a blank crystal report with the same datasource. but don't add any field into the report. and try loading that report. and let us know the result.

I believe you can't directly access the control of a page which is in iFrame.

But in firebug i have checked the address value is maintaining till the postback.
I have tested this after having breakpoint in __doPostBack method. I think there are some server codes which is resetting the values.
The code which you have posted, is the complete server code for the page?? or are there something else?

is the same happening for all of the textboxes???

Are you sure the problem is with Crystal Report.

Try commenting the following code and run the page. if the same error is coming the then problem is with something other.
CrystalReportViewer1.ReportSource = rd;

Please verify ViewState is enabled.

do you have any constructors for Loads, Stops, and CareerObj classes?
and why don't you use DataReader instead of datatable. I believe datareader is faster than dataset.

Could you please post some more description about the problem so that it will help us to answer.

Where you have written the above code. Can you please post the eventsource of the mentioned code.

Please mark this question as solved so that it will be shown as solved and help others. :)

basically .append() add the elements to the last and .prepend() add the element as the first element.

instead of .append(), why don't you use prepend() method.

Could you please post the exception for better understanding...

Have you tried with $(document).ready() ?

You have specified ValidationGroup="Name1". So please check if any client validation fails.

i think your update statement should be:
UPDATE Admin_Branch set BranchName=@BranchName where BranchCode=@original_BranchCode

Are you looking for a perticular control?
if so then the following code may help:
GridView1.HeaderRow.FindControl("[ControlName]") as [ControlType]

Yes you can update using Jquery, which is complex to implement but a recommendable solution.
But also you can put that label inside update panel and have a timer control to refresh the label in a certain interval.

The fields which you don't want to modify, you can set ReadOnly property to True for that column. And regarding dropdown controls in some places you needs to add a templatefield instead of bound fields.

Example :
<asp:TemplateField ShowHeader="False">
<edititemtemplate>
<asp:DropDownList ID="drpItems" runat="server">
<asp:ListItem Text="Item1">
<asp:ListItem Text="Item2">
<asp:ListItem Text="Item3">


<itemtemplate>
<asp:Label ID="lblItem" runat="server" Text='<%# Eval("_modifyIp") %>'>



Please refer the below link to get more details
http://www.asp.net/web-forms/tutorials/data-access/custom-formatting/using-templatefields-in-the-gridview-control-cs

:)e.NewValues is a collection.
So if the fields are the part of GridView then the entries will be there in the collection and you need to update the values.
And if the fields are not part of GridView then you need to add those values to the collection.

So the code will be as below:

e.NewValues.Add("_modifyTime", DateTime.Now.ToString());
e.NewValues.Add("_modifyIp", Request.UserHostAddress);

Hope this helps. :)

my pleasure... :)

If this is the requirement then while populating the datasource for gridview you can store the IP address...
or you can try with the following code :

protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
e.NewValues["_modifyTime"] = DateTime.Now.ToString();
e.NewValues["_modifyIp"] = Request.UserHostAddress;
}

Are these values part of GridView???

I have posted the solution in answer section and you can mark that as answered. :)

I think you can directly use the Javascript functions written in the Child Page in the Master Page.
Note: if the child page doesn't contains the methods, which are intended to be invoked in master page, then invoking those method will throw exceptions.

As per my understanding, you need to create DataSource dynamically based on your requirement and bind that to the grid.

If the above solution helps then please mark the question as answered to help others.. :)

Hi,

If the DatakeyName is _id then why are you writing such a long condition while updating or deleting.

Where is the mapping of original_column* and the actual values?

Please try with the following code for Update

UPDATE [tbl_video]
SET [_videoName] = @_videoName,
[_videoUrl] = @_videoUrl,
[_category] = @_category,
[_subCategory] = @_subCategory,
[_createdBy] = @_createdBy,
[_createdIp] = @_createdIp,
[_createTime] = @_createTime,
[_modifyIp] = @_modifyIp,
[_modifyTime] = @_modifyTime
WHERE [_id] = @original__id

Could you please check your event log and check for exact error?
From the above description one can't know the type of error and its cause.

Is the combobox inside the datagridview?

Hi Ashvin,

how a class can be declared as :

public void class X

is it valid to write void while declaring a class ?

the above program looks incorrect to me. Compile time error.

Hi, Do you mean to refresh the page?
Please share the code for better understanding. :)

Try with the following code:

write the following page design:
<head runat="server">
<title></title>
<script type="text/javascript" language="javascript">
var remain;
function countDown() {
displayTimer(remain);
remain = remain - 1;
if (remain == 0) {
window.location = "result.aspx";
}
else {
document.getElementById("hdnTimeRemained").value = remain;
setTimeout("countDown()", 1000);
}
}
function readCounter() {
remain = document.getElementById("hdnTimeRemained").value;
countDown();
}
function displayTimer(secs) {
var hr = Math.floor(secs / 3600);
secs = secs % 3600;
var min = Math.floor(secs / 60);
var sec = secs % 60;

document.getElementById("lblTime").innerHTML = hr + ":" + min + ":" + sec;
}
</script>
</head>
<body önload="readCounter();">
<form id="form1" runat="server">
<div id="lblTime">
</div>
<asp:HiddenField ID="hdnTimeRemained" runat="server" />
<div>
<asp:Button ID="btnNext" runat="server" Text="Next" />
</div>
</form>
</body>
</html>

In the code behind's page_load event write the following:

protected void Page_Load(object sender, EventArgs e)
{
if (!this.IsPostBack)
hdnTimeRemained.Value = "3600";
}

hope this will help... :)

A quick question:

Where have you kept the backup file which you are trying to restore?

Hi Veena,

Could you please post the error message please??

Could you please elaborate your question ?
Question is not so clear...

Please check your connection string. It seems there is some problem with the connectionstring.

Hi Prafulla,

Could you please provide the code for onClick event, so it will be easier to understand to cause.

and while replying please reply to the comment, so that we will get notification. :)

instead of

AttachDbFilename=..\App_Data\Astronomy.mdf;

try with

AttachDbFilename=App_Data\Astronomy.mdf;

yes.. you can store settings in appsetting section of App.config (incase of windows application) or web.config (incase of web application).
and you can access that using the following:

string path = System.Configuration.ConfigurationManager.AppSettings["<settingname>"];

thanks,
chinmaya

Hi Prafulla,

Just a quick question. Do you have any "Select" button in the grid?

Thanks,
Chinmaya

yes.. I am also having same view as Nitin. :)
Need to check whether "Chkbox" control exists in the panel or not.

Add a new column to datasource called RowNum which will have row number.
and change your code as follows:

<div id='prm-hp_n<%# Eval("RowNum") %>s' class="slide" style="display:none;">

hope this helps.

DropDownList[] arr = { ddlvnameri1, ddlvnameri2 };

for (int i = 0; i < arr.Length;i++ ) {
arr[i].DataSource = dt;
arr[i].DataTextField = "vehicle_name";
arr[i].DataValueField = "vehicle_id";
arr[i].DataBind();
}

which problem you are talking about??

;)

actually you are creating a blank DataTable in the for loop, which is getting binded with dropdowns, so no data is displayed...

I have modified your cde... please try with the following ...

SqlDataAdapter da1 = new SqlDataAdapter("select * from vehicle_category", con);
DataTable dt = new DataTable();
da1.Fill(dt);

DropDownList[] arr = {ddlvnameri1, ddlvnameri2 };
foreach (var d in arr) {
d.DataSource = dt;
d.DataTextField = "vehicle_name";
d.DataValueField = "vehicle_id";
d.DataBind();
}

are you getting any error message?

I guess the question is about displaying the dropdown list in alphabetic manner (sorted order).

If this is the requirement then you can apply sorting on data source...

List<string> list = .....; // logic to get the list of data to display
list.Sort((a, b) => string.Compare(a, b));
DropDown1.DataSource = list;
DropDown1.DataBind();

Hope this helps...

Dim sql As String = "select * from court where courtid='" & ddlfromsec.SelectedValue & "'"

As per my understanding form the posted code, you are applying equal operator on primarykey field (courtid), it always returns only one record, and thus shows only one record everytime.

try with the following:

Dim sql As String = "select * from court"

Try with the following:

private void cb_Faculty_Code_SelectedIndexChanged(object sender, EventArgs e)
{

int irows = 0;
try
{
sql = "Select [Available_date],[Session1],[Session2],[Session3],[Session4] from Tb_Faculty_Availability where Faculty_code = '" + cb_Faculty_Code.Text.ToString() + "'";
// method to fill into dataset
DataSet ds = .........; // Fill DataSet
DGVCalendar.DataSource = ds;
DGVCalendar.DataBind();// if it is a web application. in case of windows application this line is not needed.
}
catch (Exception ex)
{
MessageBox.Show(ex.ToString(), "Error");
return;
}

there are 3 observations:

1.
if (str=="" AND st1=="")
in the above line AND is invalid instead you should use && operator.

2.
xmlhttp.open("GET","http://www.tndte.com/Result/Default2.aspx?Value="+str"regul="+st,true);
here parameters are not properly given, rather you should write as follows:
xmlhttp.open("GET","http://www.tndte.com/Result/Default2.aspx?Value="+str+"®ul="+st,true);

3.
var s = document.getElementById('reg').value;
var ss = document.getElementById('s1').value;

where as in the html design you don't have any control with id 'reg' and 's1'. you have assigned name to the controls but ids are not given.
<input type="text" name="reg"/>

please correct these and try to invoke.

happy to help... :)

What I believe, In case of checkbox if you are accessing through request.forms[], then you will get value="on" if checkbox is selected, otherwise you will get null.

It will be better if you can provide the design code of the page. From the code which you are provided, it is not very clear.

then you need to use relative path which starts from the application folder.
for example if the images folder is there in one-level up as the application folder then you need to write as follows:
string ImgExist = Path.Combine(path, "../images/" + stamp + ".jpg");

And if it inside a sub-folder (example the folder name is : resources) of application directory then you need to write as follows:
string ImgExist = Path.Combine(path, "resources/images/" + stamp + ".jpg");

Hope this helps. :)

try with the following code:

string path = Assembly.GetExecutingAssembly().Location;
string ImgExist = Path.Combine(path, "images/" + stamp + ".jpg");

The above code will work if images is a folder in the same directory where the executable resides.
