GridView RowCommand is not firing
Posted on 2013-01-07
Hi,
This is the GridView markup and Grid_RowCommand is not firing.
When LinkButton is clicked it has to fire the Grid_RowCommand. But it is not.
Please look into the markup and code and let me know your suggestions.
<asp:GridView ID="grd1" runat="server" SkinID="GridView10RowsSort
OnRowDataBound="Grid_RowDa
<Columns>
<asp:BoundField DataField="Number" HeaderText="Number" SortExpression="Number" />
<asp:TemplateField HeaderText="Amount">
<ItemTemplate>
<asp:LinkButton ID="btnAmt" runat="server" Text='<%# Bind("AMOUNT")%>'
CommandName="Select"></asp
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Type">
<ItemTemplate>
<asp:Label ID="lblDesc" runat="server" Text='<%# Bind("DESCRIPTION")%>'></a
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Date">
<ItemTemplate>
<asp:Label ID="lbldate" runat="server" Text='<%# Bind("Date")%>'></asp:Labe
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Time">
<ItemTemplate>
<asp:Label ID="lbltime" runat="server" Text='<%# Bind("TIME")%>'></asp:Labe
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Name">
<ItemTemplate>
<asp:Label ID="lblname" runat="server" Text='<%# Bind("Name")%>'></asp:Labe
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
protected void Grid_RowCommand(object sender, GridViewCommandEventArgs e)
{
GridView grd = (GridView)sender;
try
{
int iRowIndex = Convert.ToInt32(e.CommandA
switch (grd.ID.ToString())
{
case "grd1":
{
LinkButton lnk = (LinkButton)grd1.Rows[iRow
ViewState["SelectedRow"] = grd1.Rows[iRowIndex].Cells
txtDate.Text = grd1.Rows[iRowIndex].Cells
txtAmount.Text = lnk.Text.Trim();
txtType.Text = grdTrans.Rows[iRowIndex].C
break;
}
}
}
catch (Exception ex)
{
string s = ex.Message;
}
finally
{
}
}
Do I need to change anything please.
Thanks

Make sure, you display any error on catch block .
protected void Grid_RowCommand(object sender, GridViewCommandEventArgs e)
{
GridView grd = (GridView)sender;
try
{
int iRowIndex = Convert.ToInt32(e.CommandArgument);
switch (grd.ID.ToString())
{
case "grd1":
{
LinkButton lnk = (LinkButton)grd1.Rows[iRowIndex].Cells[1].Controls[0];
ViewState["SelectedRow"] = grd1.Rows[iRowIndex].Cells[0].Text.Trim();
txtDate.Text = grd1.Rows[iRowIndex].Cells[3].Text.Trim();

How can we display the error in the catch block,it's not entering into try block.
ViewState is enabled.
I changed the link button from template column to buttonfield in the .aspx page.Now the row command is firing.How to access the button filed in the row command.
I tried the following.
<asp:ButtonField runat="server" ButtonType="Link" headerText="Amount" datatextfield="AMOUNT" CommandName="Select" />
protected void Grid_RowCommand(object sender, GridViewCommandEventArgs e)
{
GridView grd = (GridView)sender;
try
{
int iRowIndex = Convert.ToInt32(e.CommandA
switch (grd.ID.ToString())
{
case "grd1":
{
int index = Convert.ToInt32(e.CommandA
GridViewRow mySelectedRow = (GridViewRow)grdTrans.Rows
txtAmount.Text = ((LinkButton)mySelectedRow
txtType.Text = ((TextBox)mySelectedRow.Fi
txtDate.Text = ((TextBox)mySelectedRow.Fi
txtDate.Text = grd1.Rows[iRowIndex].Cells
txtAmount.Text = lnk.Text.Trim();
txtType.Text = grdTrans.Rows[iRowIndex].C
break;
}
}
}
catch (Exception ex)
