gridview复选框和按钮单击事件 [英] gridview check box and button click events

问题描述

我需要获取该列的值，该列是复选框上的模板字段以及gridview的按钮单击事件

我有gridview控件，有3列用于行
第一列具有复选框
第二列字符串值
和第三列按钮
当我选中复选框时，我希望在按钮上显示第二列的值.
谁能给我建议解决方案

谢谢inadvance

解决方案

通过使用此代码，您具有单击了该按钮的gridview行.
在按钮的onclick事件中:

Button btn = (Button)sender;
GridViewRow row = (GridViewRow)btn.NamingContainer;

通过使用此代码，您可以在gridview行中单击该复选框.
在复选框的onselectedChanged事件中:

CheckBox chkbx = (CheckBox)sender;
GridViewRow row = (GridViewRow)chkbx.NamingContainer;
if (chkbx.Checked)
{
 /// your code here to do with the textbox what ever you need to do.

}

我无法给出更精确的答案，原因是我不知道复选框或按钮是否在第2列中显示了值

    AutoGenerateColumns="False" DataKeyNames="Relationship" Height="40px" WIDTH="450px"

解决方案

By using this code you have the gridview row in which the button was clicked.
in the onclick event of your button:

Button btn = (Button)sender;
GridViewRow row = (GridViewRow)btn.NamingContainer;

By using this code you have the gridview row in which the checkbox was clicked.
in the onselectedChanged event of your checkbox:

CheckBox chkbx = (CheckBox)sender;
GridViewRow row = (GridViewRow)chkbx.NamingContainer;
if (chkbx.Checked)
{
 /// your code here to do with the textbox what ever you need to do.

}

I cannot give a more precize answer cause I do not know whether the checkbox or the button shows the value in column 2

  <asp:GridView ID="grdFmlHist" runat="server" AllowPaging="True" Enabled ="False"
    AutoGenerateColumns="False" DataKeyNames="Relationship" Height="40px" WIDTH="450px"

    <PagerSettings Mode="NumericFirstLast" />
    <RowStyle BackColor="WhiteSmoke" BorderColor="CornflowerBlue" ForeColor="Black"
        Height="30px" />
    <Columns>
    <asp:TemplateField HeaderText="S.No">
          <ItemTemplate>
              <asp:CheckBox ID="chkSelect" runat="server" />
        </ItemTemplate>
         </asp:TemplateField>
         <asp:TemplateField HeaderText="S.No">
          <ItemTemplate>
            <%# ((GridViewRow)Container).RowIndex + 1%>
        </ItemTemplate>
        </asp:TemplateField>
        <asp:BoundField DataField="Relationship" HeaderText="Relationship" />
        <asp:BoundField DataField="Disease" HeaderText="Disease" />
        <asp:BoundField DataField="Dates" HeaderText="Dates" />
        <asp:TemplateField>
        <ItemTemplate>
            <asp:Button ID="btnDisplay" runat="server"  /></ItemTemplate>
        </asp:TemplateField>
      </Columns>
    <FooterStyle BackColor="Silver" Height="25px" />
    <PagerStyle BackColor="DarkGray" />
    <HeaderStyle BackColor="#000084" Font-Bold="True" ForeColor="White" />
