问题描述

我有一个带有删除和编辑按钮的Gridview

I have a Gridview with delete and edit buttons looks like

<asp:GridView ID="grdTrackedItems" runat="server" AutoGenerateColumns="False" Width="330px"
            BorderStyle="None" OnRowDataBound="OnRowDataBoundTrackedItems" OnRowDeleting="OnRowDeletingTrackedItems">
            <Columns>
              <asp:TemplateField HeaderText="Name">
                <ItemTemplate>
                  <asp:Label ID="lblItem" runat="server" Text='<%# Eval("Item") %>' />
                </ItemTemplate>
              </asp:TemplateField>
              <asp:TemplateField>
                <ItemTemplate>
                  <asp:ImageButton ID="imgDelete" runat="server" ImageUrl="~/Resources/Images/Delete.png"
                    Height="12" Width="12" ToolTip="Delete" CommandName="Delete" />
                </ItemTemplate>
                <ItemStyle Width="22px" />
              </asp:TemplateField>
              <asp:TemplateField>
                <ItemTemplate>
                  <asp:ImageButton ID="imgEdit" runat="server" ImageUrl="~/Resources/Images/Edit.png"
                    Height="12" Width="12" ToolTip="Edit" />
                </ItemTemplate>
                <ItemStyle Width="22px" />
              </asp:TemplateField>
            </Columns>
          </asp:GridView>

我在页面底部有一个文本框和保存"按钮.当我从gridview单击编辑按钮时，我想在文本框中显示项目名称.我该怎么办?

I have a text box and Save button on bottom of the page. I want to display the item name in the textbox when I click on the edit button from gridview. How can I do this?

推荐答案

为RowEditing事件提供处理程序，然后在该处理程序中更新文本框.

Provide a handler for the RowEditing event, and then update your textbox in that handler.

<asp:GridView ID="grdTrackedItems" runat="server"
             AutoGenerateColumns="False" Width="330px"
            ...
             OnRowEditing="EditRecord">
            <Columns>


protected void EditRecord(object sender, GridViewEditEventArgs e)
{
    Label lbl = (Label)grdTrackedItems.Rows[e.NewEditIndex].Cells[0].FindControl("lblItem");


    MyTextBox.Text = lbl.text;
}
