hi yeah if they are on the same page but i want to find the label in another place and there i can not find (imgid) i think i should use something like Repeater.Items.FindControl("imgrid") but that dont work

What do you mean same page? Are you trying to find something on a different page?

Kurac1 19-Apr-13 16:29pm

they are not in same class

That doesn't matter. Your code indicates you are adding it to the repeater as a child so Repeater.FindControl should work.

it dont work var label = new Label();
foreach (var v in RepeaterStrongestSkillsMax2.Controls)
{
label.FindControl("img");
}

That's because you are trying to find a control within the label. You need to not do a foreach and just do RepeaterStrongestSkillsMax2.FindControl(controlID); You want to find a control in the repeater. Actually, it's probably repeater.item.findcontrol but depends on where you are doing this. Also, just look at Repeater.Controls and try to find where your stuff is ending up.

dont get it to work i have create a simple asp repeater in the asp i have not written anything in the repeater , i only do var lbl=new label(); and var img=new image(); and then repeater.controls.add and not i am trying to find the controls because i want to make them as strings lbl.rendercontrol, but i first need to find the label from my repeater

"but i first need to find the label from my repeater" - Right, you'll need to use FindControl on your repeater. What event are you doing this in? What is Repeater.Item.Controls[0]?

this is my code private void SetSkillAndLevelMax3()
{
int count = 0;
foreach (var relevantSkillsStrongest in ListBoxRelevantSkillForMission.Items)
{

var lbl = new Label();
lbl.ID = "skill" + count++;

var img = new Image();
img.ID = "pie" + count++;

string valueTextBox = relevantSkillsStrongest.ToString();
int indexOf = valueTextBox.IndexOf("-", StringComparison.Ordinal);
string value = valueTextBox.Substring(0, indexOf - 1);
lbl.Text = value + " ";

string valueLevel = relevantSkillsStrongest.ToString();
int indexOff = valueLevel.IndexOf("-", StringComparison.Ordinal);
string levelValue = valueLevel.Substring(indexOff + 2);

if (levelValue == "Beginner")
{
img.ImageUrl = @"~/_layouts/images/Cv.Knowit/pie-1-4.png";

}
else if (levelValue == "Intermediate")
{
img.ImageUrl = @"~/_layouts/images/Cv.Knowit/pie-2-4.png";
}
else if (levelValue == "Advanced")
{
img.ImageUrl = @"~/_layouts/images/Cv.Knowit/pie-3-4.png";
}
else if (levelValue == "Expert")
{
img.ImageUrl = @"~/_layouts/images/Cv.Knowit/pie-4-4.png";
}

RepeaterStrongestSkillsMax2.Controls.Add(img);
RepeaterStrongestSkillsMax2.Controls.Add(lbl);
}

}

Don't use for loop over here..User foreach for this..
