Event On Row Select

[Matt Tapia]

Is there a way to fire a server-side event based on a row select of a rad-grid? Basically, I want to take a column value (that is the key value for the dataset) and use that to re-direct the page to a different page to view more information based on that key value. Right now, I can select a row, and then have a button that does the same thing  based on the selected row, but I want to eliminate a click. Also, is there any way to make it only fire on a double-click event?

Hello,

The ItemCommand event of grid fires when you select the row. You can access the row values as shown below.

C#:

    protected void RadGrid1_ItemCommand(object source, GridCommandEventArgs e)
    {
        if (e.CommandName == "Select")
        {
            GridDataItem item = (GridDataItem)e.Item;
            Label1.Text = item["CompanyName"].Text;

        }
    }

The KB Article shows how to perform postback when double-clicking the row.

I tried the onItemCommand, but nothing happened...anything I need to change with my datagrid properties?

<telerik:RadAjaxPanel runat="server">
    <telerik:RadGrid runat="server" ID="rgAssignedClaims" Skin="WebBlue"
        AllowPaging="true" AllowSorting="true" PageSize="10"
        AllowFilteringByColumn="true"
        onitemcommand="rgAssignedClaims_ItemCommand" >
        <ClientSettings>
            <Selecting AllowRowSelect="true" EnableDragToSelectRows="false" />
        </ClientSettings>

        <MasterTableView DataKeyNames="ClaimReviewID" TableLayout="Fixed" AutoGenerateColumns="false" >
            <Columns>
                <telerik:GridBoundColumn DataField="ClaimReviewID" HeaderText="Claim Review ID" AllowFiltering="false" />
                <telerik:GridBoundColumn DataField="OrderID" HeaderText="Order ID" AllowFiltering="false" />
                <telerik:GridBoundColumn DataField="PatientID" HeaderText="Patient ID" AllowFiltering="false" />
                <telerik:GridBoundColumn DataField="LastName" HeaderText="Patient Name" AllowFiltering="false" />
                <telerik:GridBoundColumn DataField="ClaimReviewStatusDescription" HeaderText="Status" AutoPostBackOnFilter="false" />
                <telerik:GridBoundColumn DataField="CreateDate" HeaderText="DOS Date" AllowFiltering="false" />
            </Columns>
        </MasterTableView>
        <PagerStyle Mode="NextPrevAndNumeric" />
    </telerik:RadGrid>
</telerik:RadAjaxPanel>
<asp:Label ID="lblTest" runat="server" Text="xx"></asp:Label>

C#

protected void rgAssignedClaims_ItemCommand(object source, GridCommandEventArgs e)
        {
            if (e.CommandName == "Select")
            {
                GridDataItem item = (GridDataItem)e.Item;
                lblTest.Text = item["ClaimReviewID"].Text;

            }
        }

Hello Matt,

I guess following approach is suitable for you.

aspx:

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
    <AjaxSettings>
        <telerik:AjaxSetting AjaxControlID="rgAssignedClaims">
            <UpdatedControls>
                <telerik:AjaxUpdatedControl ControlID="rgAssignedClaims" />
                <telerik:AjaxUpdatedControl ControlID="lblTest" />
            </UpdatedControls>
        </telerik:AjaxSetting>
    </AjaxSettings>
</telerik:RadAjaxManager>

    <telerik:RadGrid runat="server" ID="rgAssignedClaims" Skin="WebBlue"
        AllowPaging="true" AllowSorting="true" PageSize="10"
        AllowFilteringByColumn="true"
        onitemcommand="rgAssignedClaims_ItemCommand" >
        <ClientSettings EnablePostBackOnRowClick="true">
            <Selecting AllowRowSelect="true" EnableDragToSelectRows="false" />
        </ClientSettings>
        <MasterTableView DataKeyNames="ClaimReviewID" TableLayout="Fixed" AutoGenerateColumns="false" >
            <Columns>
             . . .
            </Columns>
        </MasterTableView>
    </telerik:RadGrid>

<asp:Label ID="lblTest" runat="server" Text="xx"></asp:Label>

cs:

        protected void rgAssignedClaims_ItemCommand(object source, GridCommandEventArgs e)
        {
            if (e.CommandName == "Select")
            {
                GridDataItem item = (GridDataItem)e.Item;
                lblTest.Text = item["ClaimReviewID"].Text;
            }
        }

[I thought you were using GridButtonColumn with CommandName "Select". Thank you for giving complete code]

thanks. it took me a bit on the double-click since it was a control within a page, but this solution worked.
