This is not an article, it's a programming forum. Page load is called before events. Always. Put it in your prerender, if you want it to fire after the button click.
There's a forum in the article, if you want to ask an author something

In my page there are two textboxes to enter dates. FromDate and ToDate textboxes. The difference between FromDate and ToDate should not be geater than 31 days. and also make sure FromDate should be less than ToDate. How to validate on client side. Am using asp.net 2.0 and c#.
Can anyone give solution?
Thanks in advance.

You can use calendar to avoid basic date validation. But if you are using simple text box to get the date then Here[^] you can get so much help.

Hello Guys.
This is just about my first post on here.
My problem on which i need some help on is as follows:
I have no problem invoking the edititemtemplate on a (Not nested) datalist.
But once i try invoking it on a nested datalist nothing happens, i have assured
that my edit button event fires. But the edititemtemplate never gets rendered.
Below you'll find a snippet of my aspx file:
<asp:DataList
ID="HeadlinesDataList"
runat="server"
OnItemDataBound="HeadlinesDataList_ItemDataBound"
DataKeyField="headlineID"
OnEditCommand="HeadlinesDataList_EditCommand"
OnCancelCommand="HeadlinesDataList_CancelCommand"
OnUpdateCommand="HeadlinesDataList_UpdateCommand">
<ItemTemplate>
<%# DataBinder.Eval(Container.DataItem, "headlineName") %>
<asp:LinkButton ID="EditHeadlineButton" runat="server" CommandName="Edit">[Edit]</asp:LinkButton><br />
!--Categories-->
<asp:DataList
ID="CategoriesDataList"
runat="server"
DataKeyField="categoryID"
OnEditCommand="CategoriesDataList_EditCommand">
<ItemTemplate>
<%# DataBinder.Eval(Container.DataItem, "CategoryName") %>
<asp:LinkButton ID="EditCategoryButton" runat="server" CommandName="Edit">[Edit]</asp:LinkButton><br />
</ItemTemplate>
<EditItemTemplate>
<asp:TextBox ID="CategoryName" runat="server" Text='<%# DataBinder.Eval Container.DataItem, "categoryName") %>'></asp:TextBox>
<asp:LinkButton ID="LinkButton2" runat="server" CommandName="Cancel">[Cancel]</asp:LinkButton>
<asp:LinkButton ID="LinkButton3" runat="server" CommandName="Update">[Update]</asp:LinkButton>
</EditItemTemplate>
</asp:DataList>
<!--/Categories-->
</ItemTemplate>
<EditItemTemplate>
<asp:TextBox ID="HeadLineName" runat="server" Text='<%# DataBinder.Eval(Container.DataItem, "headlineName") %>'></asp:TextBox>
<asp:LinkButton ID="LinkButton2" runat="server" CommandName="Cancel">[Cancel]</asp:LinkButton>
<asp:LinkButton ID="LinkButton3" runat="server" CommandName="Update">[Update]</asp:LinkButton>
</EditItemTemplate>
</asp:DataList>
<!--/Headlines-->
And here you'll see my code file for the aspx, My edit button on the nested datalist invokes this method:
CategoriesDataList_EditCommand

myHeadlines.UpdateHeadlineName((int)HeadlinesDataList.DataKeys[e.Item.ItemIndex], HeadLineName.Text);
HeadLinesDatabind();
}
}
Okay i hope somebody can give me some help.. I'm just about to give up on this.
BTW: I'm coding in Visual Web Developer 2005 Express Edition.

Hi,
ok here is the scenario:
I have two pages Transactions and Points. In the Transactions Page, I have an amount field. I was trying to pass on 10% of that amount to the Points page and directly set it in the Points Field.
I have tried several stuff. with some web help but it didn't work. I think what it is trying to do is open the page with a filter given the points= 10 example.
Please help 
Thanks a lot
IssamK

how you are opening the Points page?
If you are opening it in a new window using javascript then you can pass it in querystring or you can access the field in transaction page using opener.document.getElementById(amountfield).
And if you are redirecting it from server side using response.redirect or server.transfer then you can keep it in session before redirecting and access it from session in Points page.

Ok guys,
i am not very much aware of this code, i am just kinda debugging.
what is interesting to mention is this:
<smartone:themebutton runat="server" id="SaveButton" button-causesvalidation="True" button-commandname="UpdateData" <b="">Button-RedirectURL="Mypage.aspx?Points={TransactionRecordControl:FV:Amount}"
does it help?
thanks.

here is the straight forward code.
in transaction.aspx add a button like:
<br />
<asp:button id="btn" runat="server" onclick="redirectToPoints" text="Open Points Page" /><br />
in code behind file for transaction.aspx.cs do this:
<br />
protected void redirectToPoints(object sender, EventArgs e)<br />
{<br />
Session["tranAmount"] = youramount;
Response.Redirect("points.aspx",true);<br />
}<br />
in PageLoad function in code behind file for points.aspx.cs do this:
<br />
protected void PageLoad(object sender, EventArgs e)<br />
{<br />
if(!IsPostBack)<br />
{<br />
textboxPoints.Text = Session["tranAmount"].ToString(); <br />
}<br />
}<br />

Don't cross post it makes you rather unpopular.

hi,
well what you could try and do is to use the charAt(0) functionality of each field. and set it to upper case.
am not a pro, however this is a primitive sample code for a form with two textboxes and a button.
Dim a As String
a = TextBox1.Text
Dim b As String
b = a.Chars(0)
b = b.ToUpper()
Dim c As String
c = b & a.Substring(1, a.Length() - 1)
TextBox2.Text = c
Good luck...

I have been trying this for ages but it just doesn't seem to work. I have an image control inside a repeater control. the image control is bound to an image using the image url and databinding this when all information is called:
<asp:Repeater ID="Repeater1" runat="server" DataSourceID="SqlDataSource1">
<HeaderTemplate>
<h2><asp:Label ID="lbl_title" runat="server">T.R.E.E Team</asp:Label></h2>
</HeaderTemplate>
<ItemTemplate>
<div class="story">
<p>
<h1><asp:Label ID="lbl_Role" runat="server"><%#DataBinder.Eval(Container.DataItem, "Team_Role")%></asp:Label></h1><br />
<asp:Image ID="image_role" ImageUrl="%#DataBinder.Eval(Container.DataItem, "Team_Name")%" runat="server" />
<asp:Label ID="lbl_Name" runat="server"><%#DataBinder.Eval(Container.DataItem, "Team_Name")%></asp:Label><br />
<asp:Label ID="lbl_Description" runat="server"><%#DataBinder.Eval(Container.DataItem, "Team_Description")%></asp:Label><br />
<asp:Label ID="lbl_Telephone" runat="server"><%#DataBinder.Eval(Container.DataItem, "Team_Telephone")%></asp:Label><br />
<asp:Label ID="lbl_Email" runat="server"><%#DataBinder.Eval(Container.DataItem, "Team_Email")%></asp:Label><br />
</p>
</div>
</ItemTemplate>
</asp:Repeater>
I am using the new visual web developer 2008. If anyone knows why this is not working please let me know.

you have this line:
<asp:Image ID="image_role" ImageUrl="%#DataBinder.Eval(Container.DataItem, "Team_Name")%" runat="server" />
change it with this one and it should work:
<asp:Image ID="image_role" ImageUrl='<%#DataBinder.Eval(Container.DataItem, "Team_Name")%>' runat="server" />
you were using % instead of <% and " instead of '

Can you double check my syntax on this? I keep getting an error of too many literals in the string
ScnQuestionNo and MeasID are number fields
<br />
string strInsert ="Insert INTO DataElements (Checked, Requirement, RequirementTitle," + <br />
" MeasID,DeNr, Duplicate, LiveQuestionNo, ScnQuestionNo, DataElement, Form, QType," +<br />
" Format, [Default], SME, [User], SA, IASME, Security, [Table], FieldName," + <br />
" TQScenario, TQLive, Subtitle, DA) Values (" + Convert.ToInt16(ckChecked.Checked) + ",'" + Requirement.Text + "','" +RequirementTitle.Text+ "'," + MeasID.Text + ",'" + DeNr.Text + "'," + Convert.ToInt16(ckDuplicate.Checked) + ",'" + LiveQuestionNo.Text + "'," + ScnQuestionNo.Text + ",'" + DataElement.Text + "','" + Form.SelectedValue + "','" + QType.SelectedValue + "','" + Format.Text + "','" + Default.Text + "'," + Convert.ToInt16(ckSME.Checked) + "," + Convert.ToInt16(ckUser.Checked) + "," + Convert.ToInt16(ckSA.Checked) + "," + Convert.ToInt16(ckIASME.Checked) + "," + Convert.ToInt16(ckSecurity.Checked) + ",'" + TableName.SelectedValue + "','" + FieldName.Text + "'," + Convert.ToInt16(ckTQScenario.Checked) + "," + Convert.ToInt16(ckTQLive.Checked) + ",'" + Subtitle.Text + "'," + Convert.ToInt16(ckDA.Checked) + ")";<br />
<br />
<br />
Here's my debug output:
strInsert: "Insert INTO DataElements (Checked, Requirement, RequirementTitle, MeasID,DeNr, Duplicate, LiveQuestionNo, ScnQuestionNo, DataElement, Form, QType, Format, [Default], SME, [User], SA, IASME, Security, [Table], FieldName, TQScenario, TQLive, Subtitle, DA) Values (0,'Unk','Unk',,'DE 0.1.17',0,'',,'Last four digits of SSN','Demographics','N/A','char','',0,0,0,0,0,'Demographics','LastFour',0,0,'N/A',0)"
Now I get "Line 1: Incorrect syntax near ','."

Whoah - that is one really insecure statement. Have you considered what this is going to do if you become the victim of a Sql Injection Attack[^]? Please reconsider before you go any further down this path.

|

I am on an Govt Secure server. That is not actually out on the web. I don't have to worry about a SQL Injection Attack. I am no skilled programmer, nor trained, this is the only way I know how to do what I am doing.

What? You think that public sector workers are all above reproach. SQL Injection attacks can occur ANYWHERE where the code is running unprotected. Take the advice given in the article and use it - it will make your code easier to use AND more secure. You won't have to worry about balancing apostrophes.

Anyone that uses my application, has a security clearance, you have to have access to our network, to get to the application, if any of the people cause a SQL Injection attack. Well then, that will end with a nice prison sentence. I am reading the article, and I will always take whatever help I can get, I am not a trained programmer, the article is a bit above my head.
|
|
|
|
|
Still no excuse for poor coding techniques. As Pete said, an attack can occur ANYWHERE. Do you want to handle it after the fact, if it is ever detected at all, or prevent it from happening in the first place?
only two letters away from being an asset

The vast majority of security breaches are inside jobs.
