Hi,

Please wirte inside the .aspx.cs page

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            LinkButton lbtnSetHidden = (LinkButton)e.Row.FindControl("lbtnSetValue");
            lbtnSetHidden.Attributes.Add("onclick", "return setValueInHidden('" + e.Row.Cells[0].Text + "')");

在.aspx页面内写

<script language="javascript" type="text/javascript">
   //<![CDATA[
function setValueInHidden(cellValue) {
           document.getElementById('hdField').value = cellValue;

<asp:GridView ID="grd" OnRowCommand="grd_RowCommand">
<Columns>
<asp:TemplateField>
    <ItemTemplate>
        <asp:LinkButton ID="btn" runat="server" Text="Click" CommandName="Click" CommandArgument='<%#Eval("FirstColumnFieldName") %>'/>
    </ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>

文件后面的代码包含以下代码:

Code Behind File contain below code:

protected void grd_RowCommand(object sender, GridViewCommandEventArgs e)
{
    switch (e.CommandName)
    {
        case "Click":
        {
            string FirstColumnValue = e.CommandArgument.ToString();
            hiddenfield.Value = FirstColumnValue;
            break;
        }
        default:
            break;
    }
}

请对此投票是否有帮助.
