转发器中的Fincontrol（标签） [英] Fincontrol in repeater(Label)

问题描述

我创建了一个带有标签的转发器

I have created a repeater with a label inside

asp:Repeater ID="RepeaterStrongestSkillsMax2" runat="server">
                      <ItemTemplate>
                         <asp:Label ID="lbl" runat="server" Visible="True"></asp:Label>
                         
                       </ItemTemplate> 
                       
                        

                    </asp:Repeater>

不是我想要一个列表框并将列表框中的值添加到转发器标签

Not i am tring to foreach a listbox and add the value from the listbox to the repeater label

foreach (var relevantSkillsStrongest in ListBoxRelevantSkillForMission.Items)
            {

                

                var lbl = (Label)RepeaterStrongestSkillsMax2.FindControl("lbl");
                

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


               

                RepeaterStrongestSkillsMax2.DataSource = relevantSkillsStrongest;
                RepeaterStrongestSkillsMax2.DataBind();



            }
        }

但我没有得到任何导致转发器的原因是什么？

But i dont get any result in the repeater why?

推荐答案

你不能直接从Repeater找到控制你必须迭代到RepearterItem并从中找到控制。

You can not directly find control from Repeater You have to iterate to RepearterItem and find control from it.

foreach(RepeaterItem item in RepeaterStrongestSkillsMax2.Items){
var label = item.FindControl("lbl") as Label; //Find control from RepeaterItem
label.Text = "Your value";
}
