RadGrid TextBox Width

I am building a radgrid programmatically in the code behind. I have been unsuccessful in changing the text box width. I have tried all sorts of different variations of header-style properties along with mastertable view settings. I am new to the RadGrid controls and here is how I am currently adding my fields to the radgrid.

Dim boundColumn As GridBoundColumn
boundColumn = New GridBoundColumn()
gridPrgGrpDefinition.MasterTableView.Columns.Add(boundColumn)
boundColumn.DataField = "GrantName"
boundColumn.HeaderText = "Grant Name"
boundColumn.EditFormColumnIndex = 0
boundColumn.HeaderStyle.Width = Unit.Percentage(35)

RadSiteMap NodeTemplate Issue

The documentation seems to point out that you can use NodeTemplates when using a DataSource, but if I have a SiteMap declaritvely populated how can define a Node template and use the Text value of the Node in the template?

Code sample (see the bold black text - this is where the telerik documentation would use the databinder to bind to a datasource, but I just want to be able to determine how the node with the text value is represented. I could just type it in I guess? ):

<telerik:RadSiteMap ID="SiteMap" CssClass="subNavSiteMap" runat="server" EnableEmbeddedBaseStylesheet="False" EnableEmbeddedSkins="False">

<LevelSettings>

<telerik:SiteMapLevelSetting Level="0" ListLayout-RepeatColumns="3" ListLayout-RepeatDirection="Horizontal">

</telerik:SiteMapLevelSetting>

</LevelSettings>

<Nodes>

<telerik:RadSiteMapNode Text="Menu 1" runat="server">

<NodeTemplate>

<h3 class="Header">

[show the text from the SiteMapeNode: Menu 1]</h3>

</NodeTemplate>

<Nodes>

<telerik:RadSiteMapNode Text="SubMenu 1" NavigateUrl="" runat="server">

</telerik:RadSiteMapNode>

<telerik:RadSiteMapNode Text="SubMenu 2" runat="server">

</telerik:RadSiteMapNode>

<telerik:RadSiteMapNode Text="SubMenu 3" runat="server">

</telerik:RadSiteMapNode>

<telerik:RadSiteMapNode Text="SubMenu 4" runat="server">

</telerik:RadSiteMapNode>

</Nodes>

</telerik:RadSiteMapNode>

<telerik:RadSiteMapNode Text="Menu 2" runat="server">

<Nodes>

<telerik:RadSiteMapNode Text="SubMenu 1" runat="server">

</telerik:RadSiteMapNode>

<telerik:RadSiteMapNode Text="SubMenu 2" runat="server">

</telerik:RadSiteMapNode>

<telerik:RadSiteMapNode Text="SubMenu 3" runat="server">

</telerik:RadSiteMapNode>

<telerik:RadSiteMapNode Text="SubMenu 4" runat="server">

</telerik:RadSiteMapNode>

<telerik:RadSiteMapNode Text="SubMenu 5" runat="server">

</telerik:RadSiteMapNode>

</Nodes>

</telerik:RadSiteMapNode>

</Nodes>

</telerik:RadSiteMap>

RadGrid : OnRowSelected OnRowClick do not fire

I have a RadGrid in which first column has value as hyperlink. OnClick event of which I open a contextMenu option for that row.

The problem I am facing now is most of the Radgrid client events do not get fired. Specifically click events do not get fired when clicked on the link in the row column. How can I have OnRowClick, or OnRowSelected fired before my context menu script gets fired (which is OnClick for the hyperlink data on that row column).

Thank you

Button Click not working for the second time.

Hi,

In my aspx page, I got two List view and an add button. I am trying to remove one row from the list view and adding it to another List view. The button click event is working fine for the first time. But not working on the second time.

My settings

<telerik:AjaxSetting AjaxControlID="cmdAdd">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="lv1" /> 
                    <telerik:AjaxUpdatedControl ControlID="lv2" />             
                </UpdatedControls>
</telerik:AjaxSetting>

if I remove the above settings code, the button click event is working fine.

When I checked the generated html on firebug the following click event disappears on second time. Any idea how to fix it? am I missing any settings? Thanks for the help.

onclick="javascript:__doPostBack('ctl00$ContentPlaceHolder1$cmdAdd','')"

RadGrid vs EditMode vs accessing DataItem

Dear Telerik,

I've got a RadGrid, which has been filled with data from EntityDataSource - perfect. First column contains a GridEditCommandColumn, which fires correctly and display a FormTemplate with plenty of TextBoxes, FormTemplate contains also w RadButton with CommandName="Update" (and Cancel) - data updating works perfecty.
One of bound columns is a "Status_ID" column, which is related to another table (MSSQL). Statuses are displayed (inside FormTemplate) with RadTreeView control - also works perfectly. Unfortunately I could not find any solution for "automagical" binding "SelectedValue" of RadTreeView control with some of "Bind(column)" expression, so I've used the "NodeDataBound" event and if node.Value equals my Status_ID I select it.

Unfortunately the problem is, when I'd like to change another node from RadTreeView and fire data updating. Now I'm using such method (just after NodeClick)

var n = (e.Node);

int selectedStatus = int.Parse(e.Node.Value.ToString());

if (Respondent_Current == null)

{

int respondentId = int.Parse((this.RadGrid_Respondent.EditItems[0] as GridDataItem).GetDataKeyValue("ID").ToString());

Respondent_Current = Csi_Entities.PB_Respondent.Where(i => i.ID.Equals(respondentId)).First();

}

if (Respondent_Current != null)

{

Respondent_Current.Status_ID = selectedStatus;

this.Csi_Entities.SaveChanges();

this.RadGrid_Respondent.Rebind();

}

else { //Crap }

Which works, but it's ugly - when I update textboxes AND i update RadTreeView just after and I submit, the textboxes-changes are ignored where status is updated correctly - but it's obvious with my solution.

What would be nice:
1. When node click - update an entity object which is used by FormTemplate (not the new one).
- Maybe I should update data by accessing the (EditItems[0] as GridDataItem).DataItem as MyEntity)? Will it work?
2. On CommandName="Update" fired, all controls might be successfully updated - am I right?

Thank you for ur time & help ;)

All the best,
Przemek M. Zawada

Time interval in radscheduler

In my Radscheduler I am giving 15 minutes interval with MinutesPerRow="15" and the time panel shows time as 8:00 am,8:30 am,9:00 am etc even though there is 15 min interval in between.

How can I show 8:00 am,8:15 am,8:30 am etc in the scheduler time panel so that user can easily distinguish the time interval.

Thanks,
Soumya
