如果我有来自此行的单元格值，请在Asp.net的GridView控件中获取行的索引。

Question

I Have add a grid view control in my form and fill by the DataTable. And I create first column of every row as a link button and set same onclick event. Then I can get the text of this linkbutton.

<asp:TemplateField HeaderText="DocName">
    <ItemTemplate>
        <asp:LinkButton ID="DocName" runat="server" Text='<%# Eval("DocName") %>' OnClick="DocNameClick"></asp:LinkButton>
    </ItemTemplate>
</asp:TemplateField>

I want to get the whole row if user click the linkbutton of any row in the click event.

protected void DocNameClick(object sender, EventArgs e)
 {
     LinkButton btn = (LinkButton)sender;
     string name = btn.Text;
 }

Answer 1

You get the GridViewRow (hence all other controls in this TemplateField via FindControl ) by casting the NamingContainer propertery of the button:

protected void DocNameClick(object sender, EventArgs e)
{
    LinkButton btn = (LinkButton)sender;
    GridViewRow row = (GridViewRow) btn.NamingContainer;
    // use row.FindControl("ControlID") to get controls in other columns ...
    int rowIndex = row.RowIndex;
    string name = btn.Text;
}

Answer 2

protected void DocNameClick(object sender, System.EventArgs e)
{
    LinkButton btn = (LinkButton)sender;
    //Get the row that contains this button
    GridViewRow gvr = (GridViewRow)btn.NamingContainer;
}

Answer 3

You can get row index by following code

LinkButton btn = (LinkButton)sender;
GridViewRow row = btn.NamingContainer as GridViewRow ;
int index = row.RowIndex;

Answer 4

Add to you link the commandargument

CommandArgument='<%# Container.DataItemIndex%>' 

And in your method use it

protected void DocNameClick(object sender, EventArgs e)
{
    LinkButton btn = sender as LinkButton;
    string name = btn.Text;
    if(!String.IsNullOrEmpty(name))
        int index = int.Parse(e.CommandArgument);
}

Edit: int parse on commandargument

Answer 5

Try this:

protected void DocName_Click(object sender, EventArgs e)
{
    LinkButton btn = sender as LinkButton;
    string name = btn.Text;
}
