Programmatically changing the object datasource paramter bound with GridDropDownColumn

Hi There,

I've been trying achieve the following, but could not get it done. Looking for any of your help.

Have two dropdown column in grid (State & County)
State column is bound with Object DataSource
County column is also bound with another Object DataSource.

But, County column is related to State. When the grid is bound with DataSource, I need to display State Name and County Name in place of their IDs (Database record would have StateID & CountyID). That's the reason I chose Dropdown columns. so that I can have simple text rendered in view mode.

Here is what I'm doing..

Assign DataSource to the grid at runtime.
In the grid ItemCreated event, passing the current row's StateID to the County ODS SelectParameter.

(by expecting that ODS would get me the list of Counties for the give StateID)

Observation:

For the first row, I'm getting the County Name displayed
But for the second row, its empty.

I found that, ODS Selecting event first only once (when the grid was bound), but not for all the rows.
Note: I need grid only in view mode. Not editing rows in grid.
I tried having template columns, but could not find - how to display the county name for the corresponding id. (I do not want Combo box to be displayed, only county name has to be displayed)

Pls give your helping hand to pass out from this hurdle.
If you have any other solution, pls pass it to.

Counting upon the positive response..

        odsCounty.SelectParameters["stateSaid"].DefaultValue = "I'm assigning the currect row's state ID here";

Highlight Row on linkbutton press

Hi

I have a linkbutton in the template column. I am already triggering an event on the link button press and able to get the row. I was able to highlight it but when the next row linkbutton is clicked, i need to put the previous selected to original position. I was trying to do using row id but there is no ID for row. How can I do it differently? I was also thought may be I can put arrow in the gridgroupsplittercolumn for row selected but I don't know how to get splittercolumn id for the selected row.

Any suggestion would be appreciated.

Group Footer button to Delete Group

I have an application that manages currencies on hand for various countries. Each group is essentially a country that consists of records for each banknote denomination.

What I want to do is have a button in the group footer for each country that:

A - Is labeled "Delete United Kingdom Pound
B - When clicked, it will run an SQL query to delete all records for that country.

I have been unable to label the button.
I have been unable to get the country code needed to run the delete query.

I am developing on a Windows 7 computer using MS Visual Studio 2010.

Please let me know if I can provide more information.

Select-Unselect Child nodes based

Hello Team,

I'm facing the following issue with the Telerik Rad Tree View.

I've a tree view with multiple parent and child node relations. For instance consider a node A which has 5 child nodes a,b,c,d and e. Now i've set the CheckChildNodes property of the control to true.

Now i select the node A. So it will in turn select a,b,c,d,e. I'm unchecking a,b. Then i'm doing a postback which goes to another page and shows some content pertaining to the nodes selected. Now i click the "back" button in the browser and come to the original page. So the treeview shows the node A as selected and c,d,e as selected (and a,b as unselected). Fine till now.

Now if i unselect the node A, it is selecting all its child nodes a,b,c,d,e. If i check the node A, it is unselecting all its child nodes a,b,c,d,e. Exactly opposite!

Could some one provide some insights in this issue?

Thank you.

Regards
NLV

ajax problem with Tree in UserControl

Hi,
I have an ascx that basiocally is just a tree.
this ascx is included on aspx file.
by clicking a button I want to change the tree datasource.
i see difference using ajaxmanager and triggers. First does not work the second does.
Unfortunally i need the first case

Here is a sample
(ajax)

<%@ Register TagPrefix="qsf" TagName="RTV" Src="~/Admin/CategoriesManagement/TreeCategories.ascx" %>

.....

<form id="form1" runat="server">

<telerik:RadScriptManager ID="RadScriptManager1" runat="server">

</telerik:RadScriptManager>

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="Button1">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="CatTree1" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager>

<table style="width: 100%; text-align: left; background-color:#2e2e2e;" cellspacing="0" cellpadding="0">

<tr>

<td>

<qsf:rtv runat="server" ID="CatTree1" ></qsf:rtv>

</td>

</tr>

</table>

<asp:Button ID="Button1" runat="server" Text="Button" Width="500px" />

</form>

...

code

Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click

'change its datasource

CatTree1.setInitialPath(PathOfThreeCategory)

End Sub

second case (triggers)

<table style="width: 100%; text-align: left; background-color:#2e2e2e;" cellspacing="0" cellpadding="0">

<tr>

<td>

<telerik:RadScriptManager ID="RadScriptManager1" runat="server">

</telerik:RadScriptManager>

<asp:UpdatePanel ID="UpdatePanel2" runat="server" UpdateMode="Conditional">

<ContentTemplate>

<qsf:rtv runat="server" ID="CatTree1" ></qsf:rtv>

</ContentTemplate>

<Triggers>

<asp:AsyncPostBackTrigger ControlID="Button1" />

</Triggers>

</asp:UpdatePanel>

</td>

</tr>

</table>

<asp:Button ID="Button1" runat="server" Text="Button" Width="500px" />

same code behind..

Please May you tell me where i'm going wrong? Thank you

All this markup is in RadAjaxPanel.
The bug happens if CustomVaidator's check fails duirng item Insertion. During Item Editing it all works well.
A null reference exception happens when this bug taking place. Stack trace is below:

at Telerik.Web.UI.RadColorPicker.LoadClientState(Dictionary`2 clientState)

Thanks for your attention.

Editor Chrome Issues

I just deployed my first site with the RADEditor and the client does not like it. Here is his comment:
"Also, the editor is not very user friendly at all (tinymce was way better at this point)... where are the options for it? For example, ctrl-z doesn't work in Chrome and I have to select paragraph format first before I add content or the content won't have <p> </p>... it also adds <br> when it shouldn't, and it sometimes makes urls urls (if I copy them from a browser address bar) and sometimes it doesn't and makes them just text"

ouch.

If I can't provide answers, he will make me rip this out and go back to tinymce.

Here is the editor, note that I set the newLineMode property. Hitting Enter in IE and FF works for me.

<telerik:RadPageView ID="RadPageView2" runat="server">

<telerik:RadEditor ID="RadEditor2" runat="server" Content='<%# Bind("habitat") %>'

NewLineMode="P" ToolsFile="EditorTools.xml" Width="750" Height="472px">

<ImageManager ViewPaths="~/upload" UploadPaths="~/upload" DeletePaths="~/upload" />

</telerik:RadEditor>

</telerik:RadPageView>

Here is the toolbar.

<?xml version="1.0" encoding="utf-8" ?>

and the styles. Is there anything about this CSS that would cause the problems?

User Control inside RadAjaxManager

My Asp Panel has a usercontrol inside it...User control is dynamicaly loaded.
Asp panel is placed inside RadAjaxManager..
User control contains drop down list and text boxes..

on page load user control is loaded...
But when I change selected index of drop down list inside user control...and do a postback....I receive an error...
which says...

"Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: Failed to load viewstate. The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request. For example, when adding controls dynamically, the controls added during a post-back must match the type and position of the controls added during the initial request."
