If you want to fix the size of image then, there is a Height & Width properties in asp:Image control which you can set like
<asp:image id="Image7" runat="server" height="100px" widht="100px" imagealign="Middle">
Hope the help.

|

Inspite of specifying the height and width it is being seen in a large view that is the problem.
|
|
|
|
|
since u suggested i had tried <asp:image id="Image7" runat="server" imagealign="Middle" height="100px" width="100px">
after specifying this the image itself is invisible

Hi,
I have an editformtemplate in a grid. The edit form contains 2 radiobuttons along with other controls. During itemdatabound , i convert the values of this column in grid to yes/no. Now on itemdatabound , when the form goes into edit mode i want to get the yes/no value and after converting to true/false want to populate radiobuttons. I am having problem retrieving the Cell data from the grid in edit mode. The exception is:
Telerik.Web.UI.GridNotSupportedException: Item in insert mode does implement indexer only when the edit form is autogenerated at Telerik.Web.UI.GridEditFormInsertItem.get_Item(String columnUniqueName)
Code:
'ItemDatabound code snippet
Select Case e.Item.ItemType
Case Telerik.Web.UI.GridItemType.Item, GridItemType.AlternatingItem
Dim item As Telerik.Web.UI.GridDataItem = e.Item
'display Yes/No instead of flag 1,0
If CType(item("IsNewProduct").Text, Boolean) = False Then
item("IsNewProduct").Text = "NO"
Else
item("IsNewProduct").Text = "YES"
End If
Case GridItemType.EditFormItem 'inside template edit form
If e.Item.IsInEditMode Then
'populate controsl on template edit form
Dim item As Telerik.Web.UI.GridEditableItem = e.Item
Dim editFormItem As GridEditFormItem = CType(e.Item, GridEditFormItem)
'Below line throws error, i am trying to retrieve yes, no and chose the correct radiobutton accordingly
Dim IsNewProductValue As String = CType(item("IsNewProduct").Text, String)
'Exception is : Telerik.Web.UI.GridNotSupportedException: Item in insert mode does implement indexer only
' when the edit form is autogenerated at Telerik.Web.UI.GridEditFormInsertItem.get_Item(String columnUniqueName)
i have tried setting item as
Dim editFormItem As GridEditFormItem = CType(e.Item, GridEditFormItem)
Dim item As Telerik.Web.UI.GridEditableItem = Ctype(editFormItem.ParentItem,GridDataItem)
but this also didnt work
Please provide help in this regard. Thanks ...
Regards

Hello,
I have written a page that accepts new information and then repopulates the page when a button is clicked. This is a simple task in C#, but seems very complicated in ASP.net. The code seems to work fine on the first click, but the after the first click, the page no longer repopulates. Closer examination reveals that although the values are changed on the page, the actual values held in memory remain the same; ergo, new results are the same as the old. Now...I see that on some controls (such as RadioButton) there is an automatic postback feature, however, I cannot find this for a button. Of course, I am presuming that the Postback is the problem....OR... perhaps it's something else? My preference is not to use javascript, but I of course will if that is the only way. I am still amazed that (after all this time) ASP still has to rely on Javascript for certain features. Any ideas both welcomed and appreciated.
Thank You, Pat

Show us your Page_Load function.
|

Thank you for your reply. I have pasted the Page_Load info below. This page is brought up from a click event on another page's GridView and is supposed to populate information accordingly.
protected void Page_Load(object sender, EventArgs e)
{
medDate = CreateMedicalDate(medDate);
id = Request.QueryString["Id"];
Screening_Number = Request.QueryString["Screening_Number"];
Site_Number = Request.QueryString["Site_Number"];
Version_Id = Request.QueryString["Version_Id"];
Version = Request.QueryString["Version"];
AE = Request.QueryString["Ae"];
Serious = Request.QueryString["Serious"];
GetLastVersion();
SqlConnection Conn = new SqlConnection(CONNSTR);
try
{
string Sql = "SELECT [Id],[Period] , [Screening_Number] , [Site_Number] , " +
"[Version_Id],[Version] , [Ae] , [Frequency] , [Visit] , [VisitNumber] , [Date_Onset] , " +
"[Ongoing] , [Date_Ended] , [CTCAE] , [Serious] , [Related] , [Action] , [Outcome] , " +
"[NewConMedsY], [NewConMedsN], [SubBy] , [SubOn] , [Sae_Rpt_Status] " +
"FROM Adverse_Events WHERE [Version_Id] = @Version_Id AND [Version] = @LastVersion ";
SqlCommand Comm = new SqlCommand(Sql, Conn);
Comm.CommandType = CommandType.Text;
Comm.Parameters.Clear();
Comm.Parameters.AddWithValue("@Version_Id", Version_Id);
Comm.Parameters.AddWithValue("@LastVersion", lastCompletedVersion);
SqlDataAdapter da = new SqlDataAdapter(Comm);
DataSet ds = new DataSet();
da.Fill(ds);
LabelPeriod.Text = ds.Tables[0].Rows[0]["Period"].ToString();
LabelScreeningNumber.Text = ds.Tables[0].Rows[0]["Screening_Number"].ToString();
LabelVersion.Text = ds.Tables[0].Rows[0]["Version"].ToString();
LabelId.Text = ds.Tables[0].Rows[0]["Id"].ToString();
LabelAe.Text = ds.Tables[0].Rows[0]["Ae"].ToString();
LabelFrequency.Text = ds.Tables[0].Rows[0]["Frequency"].ToString();
LabelVisit.Text = ds.Tables[0].Rows[0]["Visit"].ToString();
LabelVisitNum.Text = ds.Tables[0].Rows[0]["VisitNumber"].ToString();
LabelDateStarted.Text = ds.Tables[0].Rows[0]["Date_Onset"].ToString();
LabelOngoing.Text = ds.Tables[0].Rows[0]["Ongoing"].ToString();
LabelDateStopped.Text = ds.Tables[0].Rows[0]["Date_Ended"].ToString();
LabelCtcae.Text = ds.Tables[0].Rows[0]["CTCAE"].ToString();
LabelSerious.Text = ds.Tables[0].Rows[0]["Serious"].ToString();
LabelRelated.Text = ds.Tables[0].Rows[0]["Related"].ToString();
LabelAction.Text = ds.Tables[0].Rows[0]["Action"].ToString();
LabelOutcome.Text = ds.Tables[0].Rows[0]["Outcome"].ToString();
RadioButtonConMedY.Checked = Convert.ToBoolean(ds.Tables[0].Rows[0]["NewConMedsY"].ToString());
RadioButtonConMedN.Checked = Convert.ToBoolean(ds.Tables[0].Rows[0]["NewConMedsN"].ToString());
LabelSubBy.Text = Session["Name"].ToString();
LabelSubOn.Text = medDate;
}
catch (Exception ex)
{
Console.WriteLine("Error : " + ex.Message);
}
SetDateDropdownBoxes();
}
There is a button on the page that is supposed to decrement a value in the LabelVersion label and re run the Sql thereby re populating the page with new information. As I said, it works on the first click, but not afterwards. Thanks for your attention. Best, Pat

And where is the button click event? Without checking for IsPostback all this will do is repopulate the controls from the database and overwrite the value you expect.
I would refactor this code to extract the all the SQL lookup code to a method so It can be called from multiple places in your code. Such as from the PageLoad event and from the button click handler

I may be confused, both posts together are the code you are using correct? If so, then as I said, you need to use IsPostBack in the PageLoad event so the controls are not overwritten each time the page is loaded, i.e. during a postback caused by the button click. And again, abstract the database code to a separate method. It will save you a lot of typing and cut & paste errors and debugging.

Yes,Yes,Yes,Yes....OK....."I SEE" said the blind man. Both you and David were right Mark, and now I GET it. When the page re posts, it is running the load event all over again, and that is overwriting the method so it appears that it is unchanged. I am so sorry that I did not understand. You are both saying the same thing.....it took a moment for it to sink in. THANK YOU both very much. I scripted it a bit different, but it is working now. I will try to mark both answers correct, as they both are. If it is not allowed, I guess I will have to stamp Mark's first only since his was sent first. I greatly appreciate the time and skill from both of you, and I hope you will sign in for me again in the future. Best regards, Pat

Well I might be a little confused on exactly which is the first click.
But anyways what you need is code like this ...
protected void Page_Load(object sender, EventArgs e) {
if (Page.IsPostBack)
{
LabelVersion label gets deincremented here
}
medDate = CreateMedicalDate(medDate);
id = Request.QueryString["Id"];
Screening_Number = Request.QueryString["Screening_Number"];
Site_Number = Request.QueryString["Site_Number"];
and so on ...

So at the time of subit, Iterate throgh all the gridview rows and which row has checkbox checked, save it in database.You can save the data in both the table using query.
Where are you actually facing problem?

|
|
|
|
Easy, your code is wrong - what else do you expect it to be?
Without seeing your code or knowing what errors you are getting someone is meant to help you fix the problem. Can you see where the problem really lies?
