Hi,

I have an Issue in GridDropDownColumn .. I want to set the (DataSourceID ,, ListTextField ,, ListValueField)
in Code-behind Dynamicaly for each Row based on some Condition.

the following Code is Changing the values of each Property but It's not binding or Reflecting anything..

Designer:

<telerik:GridCheckBoxColumn DataField="IsCustomer" SortExpression="IsCustomer"

UniqueName="IsCustomer" DataType="System.Boolean" ReadOnly="true" Visible="false" >

</telerik:GridCheckBoxColumn>

<telerik:GridDropDownColumn DataField="CustomerID" UniqueName="CustomerID"

EnableEmptyListItem="True" >

<HeaderStyle Width="120px" />

<ItemStyle Width="120px" />

</telerik:GridDropDownColumn>

<telerik:GridDropDownColumn DataField="ContactID" UniqueName="ContactID"

EnableEmptyListItem="True" >

<HeaderStyle Width="100px" />

<ItemStyle Width="100px" />

</telerik:GridDropDownColumn>

Code :

Protected Sub rgOpportunities_ItemCreated(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridItemEventArgs) Handles rgOpportunities.ItemDataBound

If (TypeOf e.Item Is GridDataItem) Then

'If (TypeOf e.Item Is GridEditFormItem AndAlso e.Item.IsInEditMode) Then

Dim editFormItem As GridDataItem = CType(e.Item, GridDataItem)

Dim Cus As GridDropDownColumn = CType(rgOpportunities.MasterTableView.Columns(8), GridDropDownColumn)

Dim Con As GridDropDownColumn = CType(rgOpportunities.MasterTableView.Columns(9), GridDropDownColumn)

If DirectCast(editFormItem("IsCustomer").Controls(0), CheckBox).Checked = True Then

Cus.DataSourceID = "odsCustomer"

Cus.ListTextField = "Name"

Cus.ListValueField = "CustomerID"

Con.DataSourceID = "odsContact"

Con.ListTextField = "Name"

Con.ListValueField = "ContactID"

Else

Cus.DataSourceID = "odsLeadHdr"

Cus.ListTextField = "Name"

Cus.ListValueField = "LeadHdrID"

Con.DataSourceID = "odsLeadDtl"

Con.ListTextField = "Name"

Con.ListValueField = "LeadDtlID"

End If

End Sub

Thanks..

Hiding the edit button

Hi,
I want to hide/disable the edit button dependent on what is in the row. Hypothetically speaking if there was one column (showing complete and uncomplete), and the edit button column, i only want the edit button to appear or be enabled on rows that were uncomplete.
Many Thanks
Ryan

RadGrid, LINQ and Parent/Child

Hiya,
I am new to the Telerik tools.

Need to use LINQ with the RadGrid to present data in a parent/child view. Is this possible? I have spent quite while trying to get it to work. Single (parent) table works fine.

I have read the tutorial and searched the forums but cannot find a reference that says the LINQ is supported at this stage by RadGrid.

Question about alignment of paging bar text

In the grid I'm running, the paging is mostly default. The paging buttons are on the left hand side of the grid.

On the far right hand side of the grid is the display of number of items in number of pages.

Is there any way to control that?

(What I'd ideally like to do is have it left aligned, right up against the buttons.)

Select all Checkboxes in Column - JavaScript

I have a page that had one column that I had to provide a "(Un)Check All" in the header. I used this code to select or unselect them all and it works fine:

Here is the js code:
function SelectAllCheckedChanged() {

var grid = window['<%= rgManufacturerDisplay.ClientID %>'];

var inputElements = grid.MasterTableView.Control.getElementsByTagName("INPUT");

var headerChecked = window.event.srcElement.checked;

var index;

for (index = 0; index < inputElements.length; index++) {

//NOTE: The GetElementsByTagName("INPUT") will return ALL input controls in the grid, so we have

//to filter to the ones that we specfically care about.

if (inputElements[index].id.indexOf("chkDistributor") != -1) {

//If the id of the control is "chkDistributor" then this is the checkbox in the Select column

//for the grid row and we need to check/uncheck it (only if it's enabled).

if (!inputElements[index].disabled) {

inputElements[index].checked = headerChecked;

}

However now I have to add a second column, and need it to do the same thing...that is select or unselect all the rows in THAT column.

I've tried a couple of things, but not yet had much success. The second column ID is chkContractor.

Anyone got any ideas of how I would do this with JavaScript?

Thanks.

Sorting and Dynamic Columns

I am running into issues when my dynamically bound grid has been sorted by Column A and on a post back, Column A is no longer present due to a user-preference change. I would like to clear the sorting if the column no longer exists so that I don't get an error on the page. Is there a way to do this?

Thanks!

<telerik:RadGrid ID="rg" runat="server" Skin="Office2010Silver" OnNeedDataSource="rg_NeedDataSource"

OnItemCommand="rgScores_ItemCommand">

<ExportSettings HideStructureColumns="true" />

<MasterTableView AllowPaging="true" AllowSorting="true" Width="100%" CommandItemDisplay="Top">

<CommandItemSettings ShowExportToExcelButton="true" ShowRefreshButton="false" ShowAddNewRecordButton="false" />

</MasterTableView>

</telerik:RadGrid>

Ajaxyfied radgrid export using 'internal' radgrid buttons

Hi

I'm using an ajaxyfied radgrid and want to use the command buttons the grid offers for export.
But Clicking on one of them does not export it shows the generated output on the page.
What I understood from all reading about this is, I have to disable ajax
for the export something like this:

<script type="text/javascript">

function RequestStart(sender, args)

{

if (args.EventTarget == "Button1")

{

args.EnableAjax = false;

}

</script>

On all the examples I've found a button, "Button1", is used to do this. How do I reference the internal buttons of the radgrid to do the same or is there a different way of doing this?
Thanks in advance

Buttons Floating out of RadGrid + Blank Cells! [IE]

Hello,

I have a RadGrid positioned inside the upper pane of a RadSplitter. I added a GridTemplateColumn to hold a RadButton with an Icon [green down arrow]. The grid is set to allow scrolling. All goes just well in Chrome; but the weird problem I am facing is that , in IE, and once the scrollbar shows, the buttons start to float out of the grid and the splitter! They even transcend the lower pane and page borders [as shown in the attached pic "wrong"]. But it's not the case when the data is accommodated inside the grid with no scrollbar [as shown in the attached pic "right"]. Also, sometimes when the cells are empty, the grid inside borders disappear in some areas and cells kind of merge as shown! Again, this happens only in IE.
I hope you can enlighten me; as this is urgent and IE is the default browser in the company I work for.

Thank you!

[Edit: oops, I don't seem to find a way to attach my demo pics. ? :)]
