GridViewRow Cells在按钮中返回空字符串单击Gridview内的事件启动。 [英] GridViewRow Cells returning empty strings in button Click Event fire-up inside Gridview.

问题描述

我对这个问题感到困惑。



我在gridview的模板字段旁边放了一个按钮，想要从特定的GridView Row返回数据当点击相应的按钮时。

I am confused with this problem.

I have put a button in side the template field of a gridview and want to return the data from that specific GridView Row when that corresponding button is clicked.

<asp:TemplateField>
                    <ItemTemplate>
                        <asp:Button ID="Button2" CssClass ="btnSkin" runat="server" Text="Answer" 
                            Width="117px" onclick="Button2_Click" />
                    </ItemTemplate>
                </asp:TemplateField>
<

In按钮单击事件fireup，我想通过创建GridViewRow元素来读取该数据。

In the button click event fireup, I want to read that data by creating a GridViewRow Element.

protected void Button2_Click(object sender, EventArgs e)
        {
            GridViewRow gvr = (GridViewRow)(sender as Control).Parent.Parent;
            Label8.Text = gvr.Cells[1].Text;
            Label10.Text = gvr.Cells[2].Text;
            Label12.Text = gvr.Cells[3].Text;
}

现在的问题是，GridViewRow Cells返回空字符串。



我该怎么办?????

Now the problem is, the GridViewRow Cells are returning empty strings.

What should I do?????

推荐答案

试试这个

protected void Button2_Click(object sender, EventArgs e)
{
 GridViewRow gvr = (GridViewRow)(sender as Control).Parent.Parent;
 txt_bx.Text=((TextBox)GridView1.Rows[gvRow.RowIndex].FindControl("id of textbox in gridview")).Text;           
}

问候..：）

当你想在gridview中触发任何控制事件时，那么控件的事件使用gridview的OnRowCommand活动。



在您的情况下请执行以下操作。

Hi,

When ever you want to fire any control event inside gridview, then instead that control's event use gridview's OnRowCommand event.

In your case do following.

<!--Aspx page-->
<asp:gridview id="YourGridID" runat="server" onrowcommand="YourGridID_RowCommand" ..="" xmlns:asp="#unknown">
      <asp:templatefield>
            <itemtemplate>
                  <asp:button id="Button2" cssclass="btnSkin" runat="server" text="Answer">
                            Width="117px" CommandName="GetRow" />
            </asp:button></itemtemplate>
      </asp:templatefield>
</asp:gridview>

//Code behind
protected void YourGridID_RowCommand(object sender, GridViewCommandEventArgs e)
{
      if (e.CommandName == "GetRow")
      {
            GridViewRow row = (GridViewRow)(((Button)e.CommandSource).NamingContainer);
            //Here i am assuming you are having label inside your gridview
            Label lbl= (Label)row.FindControl("YourLabelID");
            Label lbl1= (Label)row.FindControl("YourLabelID");
            Label lbl2= (Label)row.FindControl("YourLabelID");

            Label8.Text = lbl.Text;
            Label10.Text = lbl1.Text;
            Label12.Text = lbl2.Text;
      }
}

希望有所帮助。
