I am using a repater whose item template is having a dropdownlist. Now i want to access that dropdownlist from a button click event. Here is the code iam using :
protected void btn1_Click(object sender, EventArgs e)
{
foreach (RepeaterItem item in rptWord.Items)
{
DropDownList ddl1 = (System.Web.UI.WebControls.DropDownList)rptWord.FindControl("ddlWord");
}
}
But m getting ddl1 as null. For this i created a function which is as follows:
public void myFunction(object sender, RepeaterItemEventArgs e)
{
foreach (RepeaterItem item in rptWord.Items)
{
DropDownList la = (System.Web.UI.WebControls.DropDownList)e.Item.FindControl("ddlWord");
}
}
using this function iam able to access the repeater but i guess its not possible to call this function on button click event .
how I access /retrieve values of checkboxlist inside a repeater? My code is below..is it the same as if it was not inside a repeater? My other concern is how do I distinguish these checkboxes because basically what 's going to happen here is based on which checkbox is selected I need to query an xml file to get the location of a folder which I'm then going to zip up and allow user to download..So here's the breakdown. I have an accordion panel using jquery ui. Each panel hold a product and each product has the same checkboxes..so depending on which product the user wants to download files for which he/she will indicate by opening the accordion panel for that product and checking which checkboxes/file they want to download . So how will I know which product the user clicked the checkboxes for being that I'm using this repeater which just one ID?
[Code]....
can I still use this code or will it not work cause it's inside a repeater..also I was going to use jquery to add an onclick event to the checkbox so how can I do that now with me using this control?
[Code]....
Here's another issue..I can't even assign values to the checkboxlist using databinding..so how am I suppose to do this.. Server Error in '/ArchitectView' Application. Parser Error Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately. Parser Error Message: Databinding expressions are only supported on objects that have a DataBinding event. System.Web.UI.WebControls.ListItem does not have a DataBinding event.Source Error:

i have simple repeater control on my page:
<asp:Repeater id="Repeater1" runat="server" DataSourceID="SqlDataSource1">
<ItemTemplate>
<asp:TextBox id="txtBox1" runat="server" Text='<%#Eval("attributename") %>'></TextBox>
<ItemTemplate>
</Repeater>
I'm bounding data to repeater control by using SqlDataSource Control
bounded data is something like this:
attributeid attributename
1 color
2 size
How can I get access to attributeid values in Repeater control's ItemDataBound event handler,
I tried to use DataBinder.GetPropertyValue(container,"attribuetid"), but I can't set container, am I doing right, or maybe I should use another approach.

View 3 RepliesI have 3 buttons that change the Information being displayed in my Gridview (Previous, Today, Forward). Now management wants to SUM the Date's information by column, I have figured out how to do this by changing the BoundField to a TemplateField and then add a FooterTemplate with a SQL DataSource. When I Press either the Previous or Forward button the data does not change in my Sum'd Footer column.

I have a repeater that I have bound to a sql reader via my code behind page.
However I can't figure out how to populate the controls in my repeater in my code behind code.
At the moment I am having to specify the database field e.g productprice with the control in the .aspx page like this
<asp:Label ID="LabelUnitPrice" runat="server" Text='<%# Eval("productprice") %>'></asp:Label>
I would rather specify fields in my code behind than embedding them in the .aspx page.
I also have a subtotal label control in my repeater that I would like to populate its text property by mutiplying two of the database values e.g productprice * unitprice shown in my repeater.
I need to do this in code behind, looping through the repeater. Any idea of how I can do this in C#?
