I'm trying to access text from a ButtonField(databound), but I can't get the text if I refer to it as a TableCell. What can I do to get its text?
Markup:
<asp:GridView ID="gvClass" runat="server" CssClass="grid" HeaderStyle-Font-Bold="true" Width="100%" OnSelectedIndexChanged="gvClass_SelectedIndexChanged" DataKeyNames="ClassID" AutoGenerateColumns="False" OnPageIndexChanging="gvClass_PageIndexChanging">
<HeaderStyle Font-Bold="True" />
<Columns>
<asp:ButtonField DataTextField="ClassID" HeaderText="Class ID" CommandName="Select" />
<asp:BoundField DataField="CourseName" HeaderText="Course Name" />
<asp:BoundField DataField="WarehouseName" DataFormatString="Warehouse" HeaderText="Warehouse" />
<asp:BoundField DataField="TrainerNames" HeaderText="Trainer(s)" />
<asp:BoundField DataField="StartTime" HeaderText="Start Time" />
<asp:BoundField DataField="Duration" HeaderText="Duration" />
<asp:BoundField DataField="Course Category" HeaderText="Course Category" />
<asp:BoundField DataField="Comment" HeaderText="Comment" />
</Columns>
<EmptyDataTemplate>
<span class="italic grey">No Record Found</span>
</EmptyDataTemplate>
</asp:GridView>
Code-behind:
foreach (GridViewRow gvr in gvClass.Rows)
{
foreach (TableCell tc in gvr.Cells)
{
stringToAppend = tc.Text;
sb.Append(PRTL_UtilityPackage.FormatHtmlCharacters(stringToAppend) + " \t");
}
sb.Append("\\n");
}
The foreach (TableCell tc in gvr.Cells) comes up with an empty string when looking at the ButtonField.
You can still use the tablecell method:
protected void myGridView_DataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
// You may have to play with the index of the control
// I have found that often a GridView will place a
// Literal control as Control[0] and the LinkButton
// as Control[1]. Once you find the index, it won't
// change.
LinkButton btn = (LinkButton)e.Row.Cells[0].Controls[1];
string text = btn.Text;
}
}
