Access Value in CommandItemTemplate During NeedDataSource

Hello All,

I'm having problems accessing a value in the OnNeedDataSource event. The value is a textbox in the CommandItemTemplate. I'm using it as a custom filter while building the datasource. I've done this before but forgot how I did it. :( It seems that during the OnNeedDataSource the CommandItemTemplate has not been created yet.

Thanks,
Jerry

RadGrid GridDropDownColumn validations

Hi,

I'm quite new with asp and telerik components, so I need some help to figure this out:

i'm trying to validate GridDropDownColumns that hold Combobox's and check is text area of combobox filled with value from dropdown.

Now my problem is when I try to add custom validator in cs code side, it doesn't fire serverside validation. I don't want to add templatecollums to my grid if it's not necessary.

in itemDataBound:

if (e.Item is GridEditableItem && e.Item.IsInEditMode)

{

GridEditableItem item = e.Item as GridEditableItem;

if(item["content"].Controls[0] is RadComboBox)

{

GridDropDownListColumnEditor editor = item.EditManager.GetColumnEditor("content") as GridDropDownListColumnEditor;

TableCell cell = (TableCell)editor.ComboBoxControl.Parent;

CustomValidator validator = new CustomValidator();

validator.ServerValidate += new ServerValidateEventHandler(comboboxValidations_ServerValidate);

validator.ValidationGroup = "comboGroup";

validator.ErrorMessage = "!";

validator.ValidateEmptyText = true;

validator.ControlToValidate = editor.ComboBoxControl.ID;

cell.Controls.Add(validator);

}

Server side function not running

Hi

I have a RadGgrid witht he following template section:

<telerik:GridTemplateColumn HeaderText="Arrival" SortExpression="LocationArrival" HeaderStyle-HorizontalAlign="Center" ItemStyle-HorizontalAlign="Center" AllowFiltering="false" UniqueName="LocationArrival">
<ItemTemplate>
<asp:CheckBox ID="chkActivityArrival" runat="server" AutoPostBack="True" visible="false" OnCheckedChanged="chkActivityArrival_CheckedChanged"/>
</ItemTemplate>
</telerik:GridTemplateColumn>

However when I click the checkbox the function chkActivityArrival_CheckedChanged on the server isn't being hit. The controls visibility is controlled in the code behind.

I have the same code n other grids and they work OK, what would be causing this..

Multiselect check box column behaves inconsistently with paging

I'm trying to setup a grid with paging, filtering, grouping and multiselect turned on, including the check box column for selection. I understand that when paging and filtering, any existing selected rows will become unselected. But when I page through a grid, the row select check box column seems to become disabled - we cannot check rows to be selected after paging. Drag and drop selection continues to work and the "select all" check box still works, but the check boxes to select individual rows do not.

I have tried simplifying our grid setup to one with just multiselect and paging but the issue remains.

Also of note we are still using a 2012 release of Telerik UI for ASP.NET AJAX. We intend to update to the latest 2014 release in the next release of the software we are delivering to our client, but will need to continue to use the 2012 Telerik UI release for the current release of the client's software.

So is this a known issue with the 2012 releases of the grid UI? Is there any known fix besides upgrading to a later version of Telerik UI?

Thank you,

Eric

Open RadWindow when click on RadButton

I am trying to open a RadWindow when clicking on a RadButton (RadButton1) but it does nothing. However when i try to do the same with an asp Button (Button3) the RadWindow opens successfully. What am i missing? Thank you in advance.
Here is a piece of the code:

<div id="ContentTemplateZone" class="qsf-ib infoBox">

<asp:Button ID="Button3" Text="Open rad window from Button" runat="server" OnClientClick="openWinContentTemplate(); return false;">

</asp:Button>

<telerik:RadButton ID="RadButton1" runat="server" Text="Open rad window from RadButton" ButtonType="StandardButton"

OnClientClick="openWinContentTemplate(); return false;">

<Icon PrimaryIconCssClass="rbAdd" PrimaryIconLeft="4" PrimaryIconTop="4"></Icon>

</telerik:RadButton>

<br />

<asp:Label ID="Label1" Text="" runat="server"></asp:Label>

<script type="text/javascript">

function populateValue() {

$get("<%=Label1.ClientID %>").innerHTML = $get("<%= Textbox1.ClientID %>").value;

alert($get("<%= Textbox1.ClientID %>").value);

//the RadWindow's content template is an INaming container and the server code block is needed

$find("<%=RadWindow_ContentTemplate.ClientID%>").close();

}

function openWinContentTemplate() {

alert("open");

$find("<%=RadWindow_ContentTemplate.ClientID %>").show();

}

</script>

</div>

<telerik:RadWindow runat="server" ID="RadWindow_ContentTemplate" RestrictionZoneID="ContentTemplateZone" Modal="true">

<ContentTemplate>

<p class="contText">

Enter a value here and click the button to close the RadWindow and pass the

value to the main page.

</p>

<div class="contButton">

<asp:TextBox ID="Textbox1" runat="server"></asp:TextBox>

</div>

<p class="contText">

Via a simple JavaScript function:

</p>

<div class="contButton">

<asp:Button ID="Button1" Text="send value and close" runat="server" OnClientClick="populateValue(); return false;">

</asp:Button>

</div>

<p class="contText">

Via a simple method in the code-behind:

</p>

<div class="contButton">

<asp:Button ID="Button2" Text="send value through code-behind" runat="server" OnClick="Button2_Click">

</asp:Button>

</div>

Radgrid automatic pagesize

Good day,

we have implemented a flex layout to accommodate our typical site page setup with a formview on top and one or more radgrids at the bottom.

The flex based design uses a non stretching top space dedicated to the formview, and a stretching inferior part dedicated to the grids.

We would like to implement a dynamic pagesize solution to take advantage of our site's fluid design. We've already solved all containment challenges so the radgrid's container implements auto scroll, but because of the grids' pagesizes, the grids remain limited in vertical size and never benefit from a taller display than the 'design' one.

We would like to know how to implement a dynamic pagesize based on the grid's container height, or any equivalent paging solution that would allow our grids to resize vertically automatically and take advantage of dynamic vertical space.
