how to know the row selected clicking on 2 gridbutton ?

[RRE]

Hi,

with only one gridbutton I don't have problem.
I use event:
Protected Sub RadGrid1_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles RadGrid1.SelectedIndexChanged

But with something like this (2 or moore buttons):

<radG:GridButtonColumn CommandName="Diana" HeaderText="Dettagli" Text="[Diana]" UniqueName="Diana">
</radG:GridButtonColumn>
<radG:GridButtonColumn CommandName="Sara" Text="[Sara]" UniqueName="Sara">
</radG:GridButtonColumn>

on

Protected Sub RadGrid1_ItemCommand(ByVal source As Object, ByVal e As Telerik.WebControls.GridCommandEventArgs) Handles RadGrid1.ItemCommand
        Dim item As GridDataItem

            MyCmd = e.CommandName

            Select Case MyCmd
                Case "Diana"
                Case "Sara"
...
works
but
            item = RadGrid1.SelectedItems.Item(0)
            myKey = item("FId").Text

say me that I don't have selected item.

someone can help me?
Thanks

Hi Renato,

Try the following code snippet to access the selected item in the ItemCommand event.

VB:

     Protected Sub RadGrid1_ItemCommand(source As Object, e As GridCommandEventArgs)
         If e.CommandName = "Diana" Then

             For Each selecteditem As GridDataItem In RadGrid1.SelectedItems
                 Dim strtxt As String = selecteditem("FId").Text

             Next
         End If

     End Sub

Thanks
Shinu.

Hello Renato,

Please try to set EnablePostBackOnRowClick property to true:

<ClientSettings EnablePostBackOnRowClick="true"></ClientSettings>

Dear Daniel,

this is my ClientSettings

<ClientSettings AllowColumnsReorder="True" EnablePostBackOnRowClick="true">
            <Selecting AllowRowSelect="True" />
</ClientSettings>

but on my RadGrid1_ItemCommand

I don't receive selected items.

Simply if I try

RadGrid1.SelectedItems.Count

the result is 0

Hello Renato,

Please examine the sample website I created for your convenience and let us know whether it works as expected.

Dear Daniel,

thanks for support.
I studied your example. It works!

If I understand you suggest to use simple columns and track the click with a generic "RowClick" name that appears on ItemCommand event. This only if on my grid I don't have GridButtonColumn.

The row selection with GridButtonColumn works only with one button on a grid.
Is tat correct?

With Thanks

Renato

Hello Renato,

There is no dependency between the number of your GridButtonColumns and the discussed functionality.

I modified the example to show the same message on SelectionChanged event. I also added a couple of columns in order to test the depicted behavior. Unfortunately I'm still unable to reproduce it. Am I missing something?

I have the same problem.  In the handler for SelectedIndexChanged, the grid reports that it has no selection.  (The count is 0 on all the SelectedX attributes.  It doesn't seem to matter how many buttons there are, but instead seems to be associated with the use of SelectedIndexChanged, rather than ItemCommand.

It works fine when I call the SelectedIndexChanged handler from Page_Load, after calling SelectedIndexes.Add(new int[]{0}) to make sure there is a selection.  However, when it's called from SelectedIndexChanged, there is no selection. Also, when SelectedIndexChanged fires and the SelectedX attributes are examined from Page_Load, there is still no selection.

 

 

 

Finally, as soon as the callback completes, the selection highlighting disappears from the screen, so it is visible only as long as it takes to do the callback.

I have tried removing options from the grid, in case one of them made a difference, and also tried using ItemCommand, always with the same result.

Your sample program works fine for me.

Here is my code:

---

<

 

telerik:RadGrid ID="GridOffice" runat="server" AutoGenerateColumns="False" GridLines="None" AllowAutomaticDeletes="True" AllowAutomaticInserts="True"

 

 

AllowAutomaticUpdates="True" onrowdrop="GridOffice_RowDrop" AutoGenerateDeleteColumn="True" onitemcommand="GridOffice_ItemCommand"

 

 

>

 

 

<MasterTableView CommandItemDisplay="Bottom" EditMode="PopUp" DataKeyNames="StateKey,OfficeSeq">

 

 

<Columns>

 

 

<telerik:GridBoundColumn DataField="Text" EmptyDataText="&amp;nbsp;" HeaderText="Office" UniqueName="Office" />

 

 

<telerik:GridEditCommandColumn />

 

 

</Columns>

 

 

<EditFormSettings>

 

 

<EditColumn UniqueName="EditCol" HeaderText="Add" />

 

 

</EditFormSettings>

 

 

</MasterTableView>

 

 

<ClientSettings AllowRowsDragDrop="True" EnablePostBackOnRowClick><Selecting AllowRowSelect="True" /></ClientSettings>

 

 

<FilterMenu EnableTheming="True"><CollapseAnimation Type="OutQuint" Duration="200"/></FilterMenu>

 

</

 

telerik:RadGrid>

 

---

 

protected void GridOffice_ItemCommand(object source, GridCommandEventArgs e) {

 

 

if (GridOffice.SelectedIndexes.Count < 1) return;

 

 

string index = GridOffice.SelectedIndexes[0];

 

GridRace.DataSource =

from r in mDc.Race

 

 

where r.StateKey == GridOffice.SelectedValues["StateKey"] & r.OfficeSeq == Convert.ToInt16(GridOffice.SelectedValues["OfficeSeq"])

 

 

select r;

 

}

I figured out my problem.  I was databinding that grid in Page_Load, even on postbacks.  Once I remove that, it works fine.

The only problem is that when I reorder rows using drag & drop, the DestDataItems in the RowDrop handler are all empty if I don't databind in Page_Load.  NeedDataSource is not being called, and it's too late if I do it inside the RowDrop handler.

Anyone have suggestions?

Dear Daniel,

your example works because you add column on grid, not buttons.

You have to add at least 2 GridButtonColumn on grid to see the problem.

Thanks

Hello Renato,

Could you please modify the project I previously attached and then attach it to a formal support ticket in order to be debugged locally.

Thank you for your cooperation.

ok I will do it.

The problem is that to select a Button on a grid you have - only the first time - to select a row. Then ir will works.
