View 3 RepliesI have a datalist that has an imagebutton, I want the updatepanel to trigger each click of the imagebutton of each result. How Can I do that?
View 2 RepliesI'm trying to do: I have a webform with a datalist. The datalist shows projects (projectname, image and an imagebutton). When a visitor clicks the imagebutton two events should take place:
- First: data should be send to SQLdatabase (projectID, name of project, sessionID, datetime etc).
- Second: a pop up window must be opened to an existing webpage of the facilitator of the project, using an url which (is in my database).
The problem is my two seperate pieces of code-behind work fine, it's just that they won't work together. Here is my code: The imagebutton:
< asp:ImageButton ID="openButton" CssClass="openbutton" runat="server" ImageUrl="~/Images/openButton.png" CommandName="Sendto" CommandArgument='<%#Eval("ProjectID")%>' OnDataBinding="openButton_DataBinding" ></asp:ImageButton>
Code behind send to database:
protected void list_ItemCommand(object sender, DataListCommandEventArgs e)
{
if (e.CommandName.ToString() == "Sendto")
{
string projectId = e.CommandArgument.ToString();
bool succes = ProjectAccess.Projectopen(projectId);
}

Very new to ASP.NET (using C# behind) and am having trouble figuring out the following scenario. I have a DataList that is populated (code below) and wanted each cell to be clickable. When the cell is clicked I wanted to know the unique ID for that cell. In my code behind, my OnClick method looks like this:
[Code]....
However I never get there. It seems as if the linkbutton always refers to some javascript callback function and just reloads my form. Am I using the wrong control for what I want to do? From this click I want to look up more information from the Key (will roll up the datalist or set visible to false, then supply the new data on the same page)DataList:
[Code]....
<asp:DataList ID="listSearchResults" Border="1" BorderColor="Black"
I have something like this:

I have an asp page that has an iFrame. In the onload event of the iFrame, the javascript code copies the content of the iframe to the div. The iFrame has src="test.aspx" and hence displays the content of the test.aspx inside the div.Test.aspx page contains and imageButton, which does not show up in the iFrame.I am getting the following issues:1. the image does not show up (cannot see test.gif)2. When i click on the imagebutton link, it tries to search for test.aspx in the directory where the asp page resides inside of the actuallocation/directory of the aspx page.

View 7 RepliesI must create a few DataLists programmatically. All of them will share the same ItemTemplate. Is it possible to define this ItemTemplate in .aspx file, using wizard etc, and then create DataList programmatically and assign this template? There is information in the internet how to define both ItemTemplate and DataList programmatically, but I want to define the ItemTemplate statically and only DataList programmatically and then assign the template to it.
The problem that I encounter is that ItemTemplate tag only works inside some control tag. It looks like it is impossible to define an ItemTemplate (like e.g. resource in Silverlight) not associated with any DataList, using the wizard and design tools, and then reference this template in code during runtime.
I've got a multiline textbox inside the ItemTemplate of my Datalist, which is set to visible=false.I've got a button right above it, with the click of that button, all I want to do is make it visibleI've tried xtNewNote.visible=truethe ID of the textbox has a blue squiggly under it and I'm told that 'txtNewNote is not declared'and I've tried Dim txtNote As TextBox = CType(dlProject.FindControl("txtNewNote"), TextBox)
txtNote.visible=trueHere, I just get an object not found when it gets to the second line
I need to find which Selected Key value that was selected in the ChildDatalist inside the MainDatalist

I have gridview in my page that users can edit their data in gridview... and in this gridview I define label that I want when users click on Edit button it change label3.text:
below is code:
<asp:GridView ID="GridView1" runat="server" CssClass="DGridView1"
AutoGenerateColumns = "false" Font-Names = "Tahoma"
Font-Size = "9pt"
HeaderStyle-BackColor = "#e0e0e0"
OnPageIndexChanging = "OnPaging" onrowediting="EditCustomer"
onrowupdating="UpdateCustomer" onrowcancelingedit="CancelEdit"
GridLines = "Both" OnRowDataBound = "OnRowDataBound"
>
And .cs:
protected void EditCustomer(object sender, GridViewEditEventArgs e) {
Label Label3 = (Label)GridView1.Rows[e.NewEditIndex].FindControl("Label3");
Label3.Text = "neda";
GridView1.EditIndex = e.NewEditIndex;
BindData();
BindData1();
}
but here when I click on EditCustomer it doen't change label3.text
I have the following code in an aspx form for an asp:Repeater
<ItemTemplate>
<tr class='<%#Container.ItemIndex % 2 == 0 ? "normalRow" : "alternateRow" %>' >
<tr>
<td>
<asp:LinkButton ID="LinkButton1" runat="server">blabla
<%#DataBinder.Eval(Container.DataItem, "ListName")%>
</asp:LinkButton>
</td>
</tr>
</ItemTemplate>
Which produces a syntax error (and a sqiggle blue underline) on
<%#Databinder.Eval(Container.DataItem, "ListName")%>
the build tells me I have an invalid character in the position before the opening <%
above
This only happens after I add the conditional class for the <tr> tag
"<tr class='<%#Container.ItemIndex..."
before I add the above line (to replace the <AlternatingItemTemplate>) everythings ok.

I have a DataGridView with a ItemTeplate column, which has a HTML hyperlink (<a href....>) inside. When a user clicks on a link, a popup with a TextBox is showed to the user. Then the user can type a data. With this data, I must update the hyperlink's text in which the user clicked. All using javascript. The problem is that I don't know how to find the Hyperlink because there will be so many hyperlinks as rows in the DataGridView and they will have the same Id.
How can i find the hyperlink using javascript?
see the following code. How do I access the imageButton (or any other control I may happen to have) within the listView? In this case, I'd like to change the image of the imagebutton based on certain conditions in the code behind file while the listview is being populated.
