All the ways I can think to do this seem very hackish. What is the right way to do this, or at least most common?
I am retrieving a set of images from a LINQ-to-SQL query and databinding it and some other data to a repeater. I need to add a textbox to each item in the repeater that will let the user change the title of each image, very similar to Flickr.
How do I access the textboxes in the repeater control and know which image that textbox belongs to?
Here is what the repeater control would look like, with a submit button which would update all the image rows in Linq-to-SQL:
Edit:
This code works
Just make sure you don't blow your values away by Binding outside of if(!Page.IsPostBack) like me.. Oops.
<asp:Repeater ID="Repeater1" runat="server">
<ItemTemplate>
<div class="itemBox">
<div class="imgclass">
<a title='<%# Eval("Name") %>' href='<%# Eval("Path") %>' rel="gallery">
<img alt='<%# Eval("Name") %>' src='<%# Eval("Path") %>' width="260" />
</a>
</div>
<asp:TextBox ID="TextBox1" Width="230px" runat="server"></asp:TextBox>
</div>
</ItemTemplate>
</asp:Repeater>
And Submit Click:
protected void Button1_Click(object sender, EventArgs e)
{
foreach (RepeaterItem item in Repeater1.Items)
{
TextBox txtName = (TextBox)item.FindControl("TextBox1");
if (txtName != null)
{
string val = txtName.Text;
//do something with val
}
}
}
