Hi,
I have watched a lot of question regarding my question on Telerik forum, but it wasn't clear for me .
I have implemented filtering and sorting in Radgrid and works perfect.
Now the question  is , Is there a way to get that filtered dataset of the RadGrid?

for eg: 
Starting Datasource : {1,2,3,4,5,6.. 100}

Filtering Contain "0"
Filtered Datasource:{10,20,30,40,50,60,70,80.90,100}   

There reason I need this is because I have to bind the Filtered DataSource to a radComboBox..
I didn't see any thing in RadGrid that give me this result?

thanks,
DIP

Hi -

I am loading the editor content from an HTML file with the following code:

Private Sub LoadEditor(ByVal File As String)

 

 

Dim sr As System.IO.StreamReader

 

 

Dim fi As New System.IO.FileInfo(File)

 

 

Dim strContents As String = ""

 

 

If System.IO.File.Exists(File) Then

 

sr = System.IO.File.OpenText(File)

strContents += sr.ReadToEnd()

Editor.Content = strContents

sr.Close()

 

Else

 

 

End If

 

 

End Sub

I seem to get a few errors that I can't figure out:

1. In the HTML there is a link with a query string. e.g. 
<A href="http://www.abc.com/Default.aspx?id=118&cost=WR1841" target=_blank>
The Editor converts it to:
<A href="http://www.abc.com/Default.aspx?id=118&amp;cost=WR1841" target=_blank>

2. There are special characters like ®
The editor just displays a �

Any help will be appreciated

 

 

 

Hi,
I have a grid on my web design and set the grid's DataSource during NeedDataSource event by using following syntax:

RadGrid1.MasterTableView.DataSource = myDataSet.Tables(

"a").DefaultView

 

I tried to hide the column after the grid's DataSource is set but having code break by using following syntax:

RadGrid1.Columns(0).Visible =

False

 

After that, I tried to debug it during runtime and found out that the grid having no column even though i have set its DataSource.

Anyway to solve this out?

Thanks in advance and apprciate for the answer.

I have a project that I am in the process of replacing the drop down lists with comboboxes.

In this scenario, the drop down list will show / hide a panel (using an ajax CollapsiblePanelExtender) when a certain value is selected. This is working well (before the replacement of the ddl with the combo box).

I have added and databound the combobox, which shows the required data values.

However, when I attempt to find the combobox, the combobox is not found. The combobox is inside the insert item template of the form view and I am using master / child pages.

Here is my server side code:

 

protected void FormViewSkillDetails_DataBound(object sender, EventArgs e)

 {
    

if (FormViewSkillDetails.CurrentMode == FormViewMode.Insert)
    {
        FormViewSkillDetails.Focus(); //place the cursor on the 1st available field of the form view.
        
        //DropDownList ddl = (DropDownList)FormViewSkillDetails.FindControl("DropDownListSkillTypeInsertDisplay"); 
        RadComboBox ddl = (RadComboBox)FormViewSkillDetails.FindControl("RadComboBoxSkillTypeInsertDisplay");
        Panel p = (Panel)FormViewSkillDetails.FindControl("PanelSkillOwnHeadingInsertItem");
        RequiredFieldValidator rfv = (RequiredFieldValidator)FormViewSkillDetails.FindControl("RequiredFieldValidatorClientSideSkillOwnHeadingInsert");
        CustomValidator cvss = (CustomValidator)FormViewSkillDetails.FindControl("CustomValidatorServerSideSkillOwnHeadingInsertItemBlank");
        ddl.Attributes.Add("onchange", "JavaScript:selectInputInsertChange('" + ddl.ClientID + "', '" + p.ClientID + "', '" + rfv.ClientID + "', '" + cvss.ClientID + "');");
    }
}

Any suggestions?

 

 

 

 

 

Hi,

Hi,
We are using clientside databinding to populate our grids. To avoid "flickering" on load, the grid is bound to an empty datatable on serverside page load. However; when the grid gets databound&repainted on clientside, the rows don't get edit&delete buttons. There is just an empty whitespace where the buttons should be.

Hi,

I'm implementing my own custom RadTreeNode via inheritance. It looks something like this

public class TaggedTreeNode : RadTreeNode
{
    
    public string[] Tags
    {
        get { return (string[])ViewState["tags"] ?? new string[] { }; }
        set { ViewState["tags"] = value; }
    }

}

While I can still utilize this new property on a server side during the rendering, when I place control inside RadAjaxPanel the first ajax postback empties the contents of the property. The thing is that nodes are expanded normally via OnNodeExpand, but when some other control on the RadAjaxPanel fires a postback the information from this property is lost.

How can I create a custom property which will be persistent? It seems that no other property but described in RadTreeNode can be persisted at all during ajax postbacks.



Thank you,
Mark

I get a JS error (this._resizeType is null) on attempt to drag the RadWindow, when following conditions are met:
1. It's the Firefox browser (3.0 on my machine)
2. There is a Microsoft map script on the page

The error is somewhere in getCurrentStyle(_a0,"cursor"); call, more specifically - _2a=_27.currentStyle[_28].
I've attached the very simple example to illustrate the problem.

Would you come up with some sort of workaround?
Thanks!!!

The description is wrong since the CssFiles property is readonly.

Hi,

I have a radgrid to which I am trying to create custom filter by using http://www.telerik.com/help/aspnet-ajax/grdcustomfilteroptionswithhandling.html article. I am not able to see onClick event on GridFilterMenu class. When I add onItemClick event, I am getting the following error;

System.ArgumentException: Requested value 'null' was not found.
