WebGird IntializeRow Template Control Properties not availble in Post Back

Based on my discussion with the developer, setting the value during the InitializeRow server side event will be too late. You will need to assign the CommandName and CommandArgument earlier in the life cycle. Our suggestion will be to assigned it in the designer using the bind keyword. Here is the snippet:

<ISWebGrid:WebGridColumn Name="View_WebGridColumn" Bound="false" EditType="NoEdit"
    ColumnType="Template" Caption=" " Width="50px">
    <CellStyle ForeColor="Black" />
    <CellTemplate>
        <asp:LinkButton ID="PDF_LinkButton" runat="server" OnCommand="Command_Button_Click" 
            CommandName="QuoteView" CommandArgument='<%# Bind("CALLNUM1") %>'/>
    </CellTemplate>
</ISWebGrid:WebGridColumn>

I am using a ColumnType of "Template" for a asp:LinkButton

<ISWebGrid:WebGridColumn
	Name="View_WebGridColumn"
	Bound="false"
	EditType="NoEdit"
	ColumnType="Template"
	Caption=" "
	Width="50px"
>
	<CellStyle ForeColor="Black" />
	<CellTemplate>
		<asp:LinkButton
			ID="PDF_LinkButton"
			runat="server"
			OnCommand="Command_Button_Click"
		/>
	</CellTemplate>
</ISWebGrid:WebGridColumn>

In the WebGrid IntializeRow Server Side Event I set the following for the LinkButton

- Visible
- CommandArgument
- CommandName
- Text
- ToolTip

protected void _WebGrid_InitializeRow(object sender, RowEventArgs e)
{
	if (e.Row.Type == RowType.Record)
	{
		WebGridCellCollection _WebGridCellCollection = e.Row.Cells;

		DataRowView _DataRow = e.Row.DataRow as DataRowView;

		Int32 CallNumber_Int32 = Convert.ToInt32(_DataRow["CALLNUM1"].ToString());
		String AgentCode_String = AgentCode_TextBox.Text;

		LinkButton PDF_LinkButton = (LinkButton) e.Row.Cells[1].GetTemplateContainer().FindControl("PDF_LinkButton");

		PDF_LinkButton.Visible = false;

		PDF_LinkButton.CommandArgument = CallNumber_Int32.ToString();
		PDF_LinkButton.CommandName = "QuoteView";

		PDF_LinkButton.Text = "View";
		PDF_LinkButton.ToolTip = "View Assessment";

		// PDF

		String FileFormat_String = "";
		String FileName_String = "";
		String FilePath_String = "";

		FileFormat_String = Common.ServiceQuoteFileType(); //Desired format goes here (PDF, Excel, or Image)
			FileName_String = Common.ServiceQuoteFileName(AgentCode_String, Convert.ToInt32(CallNumber_Int32));
		FilePath_String = Common.ServiceQuoteFilePath(FileName_String);

		if (File.Exists(FilePath_String))
		{
			PDF_LinkButton.Visible = true;
		}

	}
}

The Page renders OK.

However, when I click on the Link Button, the Command_Button_Click Server-Side Event shows the CommandArgument and CommandName being empty.

protected void Command_Button_Click(Object sender, CommandEventArgs e)
{

	switch (e.CommandName)
	{
		case "QuoteView":

...
			break;
	}

}

What am I doing wrong?

How can I access the the CommandArgument and CommandName set in _WebGrid_InitializeRow in the Command_Button_Click Server Side Event?

Thanks,

Doug
