I'm getting an error: get_postBackElement().id' is null or not an object. This only occurs when I add in the RadAjaxManager, so I'm fairly sure it has something to do with that. This doesn't seem all that complicated. Am I missing something?

How can I make RadTextBox enter only numbers?

Hello,

I am using radupload.How can I check file size?

Hi there,

I am following the code from the link below. It is great. However, there are two questions that I would like to ask.
http://www.telerik.com/community/code-library/preview-thread/aspnet-ajax/grid/storing-multiple-grid-settings-in-database-via-profile.aspx

1. When I turn on AllowFilterByColumn, it works fine when I re-login. However, it does not display the value in the filter TextBox or CheckBox. For example, I put "Net 60 Days" in the filter TextBox and select "Contains". After I re-login, I see the same result, but I don't see the text "Net 60 Days" inside the filter TextBox.

2. The column reorder and sorting seem to work fine, but not for paging. How do I accomplish that?

Thank you,

Sompop

This is a profile section in my web.config.
    <profile enabled="true" defaultProvider="MyProfileProvider">
      <providers>
        <add name="MyProfileProvider" connectionStringName="myConnectionString" applicationName="/" type="System.Web.Profile.SqlProfileProvider"/>
      </providers>
      <properties>
        <add name="GridAssetSettings" allowAnonymous="false" type="GridAssetSettings" serializeAs="Binary"/>  

In .cs of the page where there is a RadGrid

protected override void Render(HtmlTextWriter writer)
{
  base.Render(writer);

  GridAssetSettings gas = new GridAssetSettings();
  gas.SaveGridAssetSettingsNames(RadGridSaveGridSettingsUserBase, "RadGridSaveGridSettingsUserBase");
  Context.Profile.SetPropertyValue("GridAssetSettings", gas);
}

protected void Page_Init(object sender, EventArgs e)
{
  if (Context.Profile.GetPropertyValue("GridAssetSettings") != null)
  {
    GridAssetSettings gas = (GridAssetSettings)Context.Profile.GetPropertyValue("GridAssetSettings");

    if (gas.Names.ContainsKey("RadGridSaveGridSettingsUserBase"))
      {
         GridSettings settings = new GridSettings(RadGridSaveGridSettingsUserBase);
         settings.LoadSettings(gas.Names["RadGridSaveGridSettingsUserBase"].ToString());
      }
    }
  }
}

Hi,

I am using radUpload to upload multiple files at a time. I need to check file's size each time user selects a file. For that using "onclientfileselected="selectedFile" in radUpload control.

Below is the code in "selectedFile" javascript function.

  var inputs = sender.getFileInputs();
  size = inputs[i].files[0].fileSize;

But it shows "size" undefined.
Before some days, I was getting correct size, but now it is not working. I've not updated Telerik's version or anything like that. What could cause this kind of issue?

Please reply at the earliest as it is live on the site.

Please ignore/delete this thread.  I tried a different approach.  Unfortunately, that didn't work out for me.  it's here if anybody wants to follow up.

Hi ,
     I am trying to bind the data to  telerick tree view dataSoure .But the data not getting into binded to the tree  view.Telerick tree view is not rendering to the page with data in ItemCommand event.


Please find the code below which I am using to bind the data tree view in ItemCommand event

 

protected void radGridHierarchies_ItemCommand(object source, GridCommandEventArgs e)

 

{

 

if (e.CommandName == "RowClick" && radGridHierarchies.SelectedItems.Count == 1)

 

{

 

int datascopeId = Convert.ToInt32(radGridHierarchies.SelectedValues["DatasourceId"]);

 

 

int dimensionId = Convert.ToInt32(radGridHierarchies.SelectedValues["DimensionId"]);

 

 

string hierName = radGridHierarchies.SelectedValues["HierarchyName"].ToString();

 

datascopeId = 11;

 

List<CharHierLevel> lstHierLevel = _presenter.GetCharHierLevelDetails(datascopeId, dimensionId, hierName);

 

radTreeCharHierLevel.DataTextField =

"HierarchyLevelName";

 

radTreeCharHierLevel.DataValueField =

"HierarchyLevelName";

 

radTreeCharHierLevel.DataFieldID =

"HierarchyLevelName";

 

radTreeCharHierLevel.DataFieldParentID =

"HierarchyLevelParent";

 

radTreeCharHierLevel.DataSource = lstHierLevel;

radTreeCharHierLevel.DataBind();

}

 

}

Note:The issue I could not find in design time .if any one got this king of issue the Immediate help will be highly appreciated

Hello everybody

I'm new in Telerik controls and this is my first post here. I'm trying to create a nested Radgrids of two levels where each record of parent will be related to two child records. I'm trying to use RadMultiPage with RadTabStrip to display the two childs as a radgrid.

The skeleton of my code is like this

I removed unnecessary code.

With this skeleton and when I click on the each records, it show the tabs but it did not list any records. I thought at the beginning that the problem of missing <ParentTableRelation> tag, but how to make the nested radgrid related to its parent. The problem that I could not use <GridTableView> because I could not integrate it with RadMultipage and RadTabStrip controls.

I want something like this example.

Any Idea plz?
