I have a 2 treeviews lets say tree1 and tree2.
tree1 has checkbox nodes
I drag and drop the checked nodes from tree1 to tree2.
On tree1_nodedrop, trying to read those checkednodes using Tree1.CheckedNodes() and it is always returning 0.
Earlier it used to work, i'm not sure whether is stop working after SP1 installation or VS2012 installation.

Telerik Current Version: 2012.2.724.40 (2012 Q2 SP1)
Code Editor: Visual Studio 2010
Framework: 4.0
Tree1 ASPX  Code:
<telerik:RadTreeView ID="tree1" runat="server" Skin="Windows7" DataFieldID="ID"

 

 

 

 

DataFieldParentID="ParentID" DataTextField="NodeText" EnableDragAndDrop="true"

 

 

 

 

CheckBoxes="true" CheckChildNodes="true" DataValueField="ValueID">

Code Behind:
Private Sub tree1_NodeDrop(sender As Object, e As Telerik.Web.UI.RadTreeNodeDragDropEventArgs) Handles tree1.NodeDrop
For Each node As RadTreeNode In tree1.CheckedNodes
// do something

 

 

 

Next

 

 

 

End Sub

What am i missing here?

 

Hi,

I am looking for custom pagination in Pivot Grid and also a way to hide the Total's Row for each group.

Basically I Have large set of data that to be shown on the grid, i want to bind only sub set of data thru custom pagination otherwise my page will suffer if i have to bind whole data to the grid.

Thanks,

Hi,

I have a radgrid on page. which has few textbox conrols, comobox, button etc in grid.
We create row dynamically. Clicking on + sign from grid footer and then it creates a new row.
On new row, we have some input boxes for user to enter info. One os theinput is such that, it has textbox control and button besieds a text box. clicking on button opens a pop up window, user will enter some value in pop window text box, whixh will be passed back from pop up to radgrid textbox control. For existing row it can access the row and textbox control for that row, however for newly created row it throws exception.

Please suggest.

Thanks,
Aditi

But this 'selectedItemID' is following null. What do I do wrong? :o/

Hi,

I'm creating a grid programmatically based on an unknown number of columns of unknown type and wish to generate multi-line footers with aggregated values. I have looked at the help page, but still not sure how to proceed.

I'm currently working in the RadGrid1_ItemDataBound method where I'm stuck at "if (e.Item is GridFooterItem)". I still need to figure out how to create the footers, populate them with text boxes, and refer to the mysterious clientID mentioned in the help article.


Thanks,
David

Hi 

I have a RadGrid on my aspx page with no columns defined as follows:

    <telerik:RadGrid ID="RadGrid1" runat="server" AllowMultiRowSelection="True" Skin="Metro"
        GroupingEnabled="true" ShowGroupPanel="True" GridLines="None" EnableLinqExpressions="false">
        <ExportSettings ExportOnlyData="true" IgnorePaging="true" OpenInNewWindow="true">
            <Excel Format="ExcelML" />
        </ExportSettings>
        <MasterTableView TableLayout="Fixed" AutoGenerateColumns="true" Width="100%" CommandItemDisplay="Top"
            AllowMultiColumnSorting="True" GroupLoadMode="Server" ShowGroupFooter="true"
            AllowSorting="True" AllowPaging="True" PageSize="20" ShowFooter="false" HeaderStyle-HorizontalAlign="left"
            FooterStyle-HorizontalAlign="Right" EnableHeaderContextMenu="true" EnableHeaderContextAggregatesMenu="true"
            AllowFilteringByColumn="True" HeaderStyle-BackColor="Black" HeaderStyle-ForeColor="White">
            <CommandItemSettings ShowExportToExcelButton="true" />
            <NoRecordsTemplate>
                <div class="NoRecordsTemplate">
                    No records to view</div>
            </NoRecordsTemplate>
        </MasterTableView>
        <ClientSettings AllowDragToGroup="true" EnableRowHoverStyle="true" AllowColumnsReorder="true"
            ReorderColumnsOnClient="true">
            <Selecting AllowRowSelect="True"></Selecting>
            <Resizing AllowResizeToFit="true" AllowColumnResize="True" EnableRealTimeResize="True">
            </Resizing>
        </ClientSettings>
        <GroupingSettings CaseSensitive="false" ShowUnGroupButton="True" RetainGroupFootersVisibility="true" />
        <PagerStyle Mode="NextPrevNumericAndAdvanced" />
    </telerik:RadGrid> 

On my code-behind page I populate the RadGrid using the GetDataTable function as follows:

    Public Function GetDataTable(ByVal query As String) As DataTable
        Dim ConnString As String = ConfigurationManager.ConnectionStrings("SQLConn").ConnectionString
        Dim conn As SqlConnection = New SqlConnection(ConnString)
        Dim adapter As SqlDataAdapter = New SqlDataAdapter
        adapter.SelectCommand = New SqlCommand(query, conn)
        Dim table1 As New DataTable
        conn.Open()
        Try
            adapter.Fill(table1)
        Finally
            conn.Close()
        End Try
        Return table1
    End Function

What I am trying to do is hide the filter icon, set AutoPostBackOnFilter=True and set filter width to auto fit programmatically.

I was able to hide the filter icon by using the following:
    <style>
        .RadGrid .rgFilter
        {
            display: none;
        }
    </style>

However, I can't figure how to set AutoPostBackOnFilter=True and set filter width to auto fit programmatically.

How can I accomplish this?

Thanks,

I need to add a default value to one of the textboxes when adding a new item in the grid

<telerik:GridTemplateColumn HeaderText="Activity ID" SortExpression="activityID" UniqueName="activityID"  >

                    <ItemTemplate>

                        <%# Eval("activityID")%>

                    </ItemTemplate>

                    <EditItemTemplate>

                        <asp:TextBox runat="server" ID="txtActivity" Text='<%# Bind("activityID") %>' />

                        <asp:RequiredFieldValidator runat="server" ID="rfvActivity" ControlToValidate="txtActivity" Display="Dynamic" ErrorMessage="*" />

                    </EditItemTemplate>

                </telerik:GridTemplateColumn>

 

 

When clicking “Add new recored” I need to pre-populate the txtActivity textbox. How can I access this from the code behind?

 

I tried this with no success

protected void RadGrid1_ItemCommand(object source, GridCommandEventArgs e)

        {

            if (e.CommandName == RadGrid.InitInsertCommandName)

            {

                GridEditableItem editedItem = e.Item as GridEditableItem;

                TextBox t = (TextBox)(editedItem.FindControl("txtActivity"));

            }

        }

 

And this:

 

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)

        {

            if (e.Item is GridCommandItem && e.Item.OwnerTableView.IsItemInserted)

            {               

                TextBox txtActivity = (TextBox)e.Item.FindControl("txtActivity");

                txtActivity.Text = "300";

            }

}

I am running out of ideas.

Please help. Thanks

Hello,
I have following code:


I would like to implement followin: After one of two dates will be picked second one should be set to the same value. How I can implement this behaviour with the simplest solution?

Have a simple question -  the purpose of this is to reduce the data transferred during every page request. 
Is there any way that when there is a postback, I can SELECTIVELY bind the data belonging to THAT specific page on the RadGrid?

The issue is that in our application, we have a grid.  We show maybe only 20 rows per page. There maybe twenty such pages.  When any one particular row is edited, I am rebinding the grid with ALL the data that fills up ALL the pages. I wish there is some way that I could rebind only the data that the user is looking at on that specific page.

Thanks in adavance for your response.
