Filtering RadGrid using comboBox

I would liek to know if there are any tutorial do help populate a comboBox in a column filter with values listed on the radGrid only.
I have a radGrid where is populated with RadGrid.Datasource. and works fine. If I try to use a ObjectDataSource to populate the comboBox I get some errors.
So how can I popluate a comboBox using the distinct RadGrid listed values?

Thank you.

GroupsChanging event does not fire to ungroup custom grouping

I have my grid's GroupsChanging event handler set up so when the use right-clicks and selects "group by" on a DateTime column, the grid groups instead on a hidden column which contains only the date. This works great.

But when I right-click on select "ungroup" on the same column, the GroupsChanging event never fires! I assume that is because that column is not actually grouped by, but it's problematic. How do I ungroup on this custom, hidden column? Perhaps there is a way I can intercept the ungroup some other way (maybe even client-side)?

FYI: If I display the date-only column, and ungroup on that, it works!

[Solved] Traversing nested tables on the client

Hi,

I have a RadGrid with a Master table (imagine that ;) ) and two levels of nested tables, so there are three levels in all. Each of the three tables has a GridTemplateColumn with asp:checkBox and some other stuff. When user checks the checkbox in Master table I would like to check the checkboxes of all its children (both levels).

I think the best way to go about it would be to get the GridDataItem in which the clicked checkbox resides, and then use get_nestedViews to get access to children etc. The only problem is I don't know how to get the GridDataItem in the first place.

Thank you for your help,
Andreja

FileExplorer Width Adjustment

I have a FileExplorer component I have placed inside a JQuery Collapsible Accordion (Width to Content and Auto Height). When the component renders the sliding of the splitter produces odd width setting on the details grid on the right. The following is the behavior I have identified.

1) The component appears to render and size properly to the fixed width and height I specify when the page initially loads.
2) When the splitter is slide the details grid reduces in size from around 400 px to about 3 px.

The results are similar to the screen shown in this thread:
http://www.telerik.com/community/forums/aspnet-ajax/file-explorer/set-height-to-100-problem.aspx

I am using JQuery UI 1.10.1 components

What I have tried to resolve it
1) Played with the width settings (percentage and px)
2) Played with writing javascript to force the width of the details grid - don't really like this solution.

Thanks

SelectedItems are not showing on server side

I have a grid setup so that I can select multiple rows using a GridClientSelectColumn... however, if I select several columns and post back to the server, when I access the selectedItems property of my radgrid, its empty.

Here is the definition of my grid and the server side code that I'm using to access the selected items.

<asp:Panel runat="server" ID="PPAContracts" >

<br/>

<telerik:RadComboBox ID="ppaPackages" DataSourceID="eSignPackagesListSql" DataTextField="epkgName"

runat="server" EmptyMessage="Choose a package" MarkFirstMatch="True"

EnableLoadOnDemand="True" DataValueField="epkgId"/>

<telerik:RadButton ID="addPPAContract" runat="server" Text="Add Contract" OnClientClicked="CheckSelectedPackage()"

onclick="addPPAContractButton_Click" />

<asp:Label runat="server" ID="errorMessage" ForeColor="Red" Text="" Visible="False"/>

<br/>

<telerik:RadGrid ID="ppaGrid" runat="server" AutoGenerateEditColumn="True"

CellSpacing="0" GridLines="None" Skin="Hay" AllowMultiRowSelection="True" ShowFooter="True"

OnNeedDataSource="ppaGrid_NeedDataSource" OnUpdateCommand="ppaGrid_UpdateCommand">

<ClientSettings>

<Selecting AllowRowSelect="True" UseClientSelectColumnOnly="True"/>

<Scrolling AllowScroll="True" ScrollHeight="600px" SaveScrollPosition="True" UseStaticHeaders="True"/>

</ClientSettings>

<MasterTableView AutoGenerateColumns="False" TableLayout="Fixed" DataKeyNames="ppaId,idorg,oid" AllowFilteringByColumn="True" >

<Columns>

<telerik:GridClientSelectColumn Reorderable="False" Resizable="False" UniqueName="selectCol"

HeaderStyle-Width="35px" ItemStyle-Width="35px"/>

here is the server side code...

protected void addPPAContractButton_Click(object sender, EventArgs e)

{

var pkgId = Convert.ToInt32(ppaPackages.SelectedValue);

if (ppaGrid.SelectedItems.Count > 0)

{

foreach (GridDataItem item in ppaGrid.SelectedItems)

{

var merged = item["mergedCb"].Text;

var oid = Convert.ToInt32(item["oid"].Text);

var did = Convert.ToInt32(item["did"].Text);

var email = item["DocEmail"].Text;

item.Selected = false;

}

I'm at a loss on why these selected items are not showing up.. any assistance would be greatly appreciated.

RadGrid inside user control - events not firing

Hi,

I have a RadGrid that sits inside an asp.net user control, with support for updating items via the grid. This all works perfectly when I add the grid in markup, however, when I add the user control programmatically to a form, the item updated event does not fire, and I am therefore unable to persist any user changes from the grid.

There are no differences other than how the grid is initially declared. Is this an asp.net issue related to user controls, or is there a known issue for RadGrids?

Thanks

Disable ComboBox with JavaScript / Style Lost?

Hello,

I use a RadComboBox in my web application. I need to disable it at a certain point using JavaScript. I referred to the Client-API on your site where you said this can be accomplished with "combo.disable()" statement.

I used this statement. However, I noticed that the combobox border has kind of disappeared; it's like it turned to a label with the selected field as text. I'd like to be able to get the combobox disabled using JavaScript but without loosing the "rcbDisabled" style from the component. I tried to disable it in the codebehind and in the markup and it showed the desired behavior. But I need to achieve the same result in JavaScript. Recommendations?

Screenshots attached to showcase:
* Enabled: to show the enabled version [Skin = Windows7].
* JavaScriptDisabled: showing the weird result I got with JavaScript's "combo.disable()"
* Markup_CodebehindDisabled: showing the desired behavior I'd like to get but using JavaScript.

Thanks!

No more _text in the rendered control?

Telerik version: 2012.3.1308.40

Hopefully this question hasn't been answered already. I searched but couldn't find anything.

Our RadMaskedTextBoxes no longer render with the _text on the inner <input element. Like in this example:

<span style="width: 100px;" class="riSingle RadInput RadInput_Default" id="ctl00_cphMasterAjax_ucPhone_rlvEdit_ctrl0_rmtbDomesticPhoneNumber_wrapper">

<input type="text" value="(515) 555-5555" controlid="ctl00_cphMasterAjax_ucPhone_rlvEdit_ctrl0_rmtbDomesticPhoneNumber" class="riTextBox riEnabled" size="15" name="ctl00$cphMasterAjax$ucPhone$rlvEdit$ctrl0$rmtbDomesticPhoneNumber" id="ctl00_cphMasterAjax_ucPhone_rlvEdit_ctrl0_rmtbDomesticPhoneNumber">

<input type="hidden" name="ctl00_cphMasterAjax_ucPhone_rlvEdit_ctrl0_rmtbDomesticPhoneNumber_ClientState" id="ctl00_cphMasterAjax_ucPhone_rlvEdit_ctrl0_rmtbDomesticPhoneNumber_ClientState" autocomplete="off" value=

"{"enabled":true,"emptyMessage":"","validationText":"(515) 555-5555","valueAsString":"(515) 555-5555","valueWithPromptAndLiterals":"(515) 555-0001"}"

>

</span>

I'm sure that prior to updating to the latest version the ID of the control would have rendered as such:
id="ctl00_cphMasterAjax_ucPhone_rlvEdit_ctrl0_rmtbDomesticPhoneNumber_text"

Either of these scenarios are possible:
a) The product (Telerik) has changed
b) Someone working on our product (we are a large team) modified some global setting somewhere and has broken things.
c) I'm officially nuts.

We have a lot of JavaScript that is no longer working, so I don't think that the answer is C. And because when I look at your online demos I see the same thing I think it goes back to A being the culprit.

Can anyone shed any light on this?

Thanks!
Thad

YAxis Extended mode bug

When the smallest values of my series are 0 then the YAxis is not extended as expected even if it's not zero based and AutoScale set to true. To test, I changed the values that were at 0 to be -10 and then the YAxis is extended to make sure values are shown. I attached an image to show the bug.
