Set page based on external event

[John]

I am running into the following scenario.

I have a combobox and a rad grid on a page.  When a value is selected in the combobox I wan to highlight the associated item in the grid.  The associated item could be on any page on the grid so the focus will need to be on the correct page and then item on the page.

I could programatically page through the pages to find and select the item but was wondering if there was an inbuilt way in the grid.

Hi John,

RadGrid does not provide such a mechanism for paging through all available pages. As you already mentioned the way is to programmatically achieve this.

I am trying the following code but it steps though the records on page 1 even after the page is changed.  What am I missing

For i = 0 To radGridItems.PageCount - 1
                radGridItems.MasterTableView.CurrentPageIndex = i
                For Each grItem As GridDataItem In radGridItems.Items
                    If grItem("Item_ID").Text = Session("EditItemID") Then
                        grItem.Selected = True
                        Exit Sub
                    End If

                Next
  Next

<telerik:RadGrid ID="radGridItems" runat="server"
        AllowPaging="True"  GridLines="None"   width="275"
         AllowAutomaticInserts="False" AllowAutomaticUpdates="False" AllowMultiRowEdit="false">
            <MasterTableView CommandItemDisplay="Top"   DataKeyNames="ITEM_ID" PageSize="4">



            </MasterTableView>
            <PagerStyle Mode="NextPrev" PagerTextFormat="{4} Page {0} from {1}" ></PagerStyle>
            <ClientSettings  EnableRowHoverStyle="true" EnablePostBackOnRowClick="true">
                <Selecting AllowRowSelect="True"  />
            </ClientSettings>

    </telerik:RadGrid>

Hello John,

Here is the sample code that I tried in application for similar scenario.Hope this helps.

ASPX:

<telerik:RadGrid ID="RadGrid1" AutoGenerateColumns="False" runat="server" DataSourceID="SqlDataSource1"
     AllowPaging="True" PageSize="3">
   <MasterTableView CommandItemDisplay="Top" DataKeyNames="EmployeeID">
       <Columns>
            <telerik:GridBoundColumn DataField="EmployeeID" UniqueName="EmployeeID">
            </telerik:GridBoundColumn>
            <telerik:GridBoundColumn DataField="FirstName" UniqueName="FirstName">
            </telerik:GridBoundColumn>
       </Columns>
   </MasterTableView>
</telerik:RadGrid>

<telerik:RadComboBox runat="server" ID="RadComboBox1" DataSourceID="SqlDataSource1"
    DataTextField="EmployeeID" DataValueField="EmployeeID" AutoPostBack="True" OnSelectedIndexChanged="RadComboBox1_SelectedIndexChanged">
</telerik:RadComboBox>

C#:

protected void RadComboBox1_SelectedIndexChanged(object sender, RadComboBoxSelectedIndexChangedEventArgs e)
   {
       RadComboBox combo = (RadComboBox)sender;
       RadGrid1.AllowPaging = false;
       RadGrid1.Rebind();
       int page = 0;
       int rowindex = -1;
       int pagesize = 0;
       foreach (GridDataItem item in RadGrid1.Items)
         {
           if (combo.SelectedValue == item["EmployeeID"].Text)
            {
                pagesize = RadGrid1.PageSize;
                rowindex = item.ItemIndex;
                page = (rowindex) / pagesize;
            }
         }
       RadGrid1.AllowPaging = true;
       RadGrid1.MasterTableView.CurrentPageIndex = page;
       RadGrid1.Rebind();
       RadGrid1.Items[rowindex - page*pagesize].Selected = true;
   }

Thanks,
Princy.
