My situation :
My Web Page has many Tab (dynamic tabs) and 1 RadGrid (grid).  When I changed position tab, grid auto generate dynamic columns.
(I must set property grid.MasterTableView.EnableViewState = false to create dynamic columns). But I can't keep settings of gird when changed to another page and move back

My code :
<code>
private int tabIndex = 0;       // variable to define tab is selected
protected void Page_Init(....)
{
          if(! string.IsNullOrEmpty(Request.QueryString["tabIndex"] )
          {
                    tabIndex = Convert.ToInt32(Request.QueryString["tabIndex"]);
          }
          else
                   tabIndex = 0;
         
          // This method create grid corresponding tab is selected
          CreateGrid(tabIndex);
}

protected void OnUnload(....)
{
       GridPersistSetting gridSetting = new GridPersistSetting (grid);
       Session["grid" + tabIndex] = gridSetting.SaveSettings();
}

protected voi Page_Load(....)
{
        if (!IsPostBack)
        {
                  ....................
                  if(Session["grid" + tablndex] !=null)
                  {
                              GridPersistSetting gridSetting = new GridPersistSetting (grid);
                              gridSetting.LoadSettings(Session["grid" + tabIndex].ToString());
                  }
        }
}

protected void Tab_Click(...)
{
         Response.Redirect("Demo.aspx?tabIndex = " + e.tabIndex)
}
</code>

I do same as your example (gridSetting.LoadSettings() in Page_Init() and and gridSetting.SaveSettings in Render()) but it not success so I must changed as above (on PageLoad and UnLoad)
Can you give me a solution ?
Thanks you.

When a GridDateTimeColumn is bound to a nested object (e.g. DataField="SomeObject.DateField"), column sorting is broken. The sorting appears to be based on the alphanumeric order. Here is the test code below with a workaround and a workaround attempt that causes an exception:

default.aspx:

default.aspx.cs:

You will notice that the first column "ParentObj" sorts fine since the bound property is part of the data object. The second column "ChildObj" is bound to a nested/child object of the main data object. This one does not sort properly. The third column "WorkAround1" is a way to work around the problem using a GridTemplateColumn and a SortExpression using .ToString("s"). Since using a GridTemplateColumn is kind of cumbersome, I thought I'd try adding the .ToString("s") to the SortExpression of a GridDateTimeColumn, but this causes an exception. This is demonstrated when trying sort the "WorkAround2" column. Although this exception should probably fixed anyway (it doesn't make sense that it works for a GridTemplateColumn and not any other kind of bound column), getting the grid to support sorting on a DateTime property of a nested object either way is fine with me.

Hi guys,

I just got a issue with RadComboBox + RadAjaxManager.
The Scenaria:

Two cbb1 and cbb2 on the web page.
I use RadAjaxManager to update cbb2 when cbb1 posted back.
And when cbb1 selectedindex changed, pop up an new window.

but whatever I setup for RadAjaxManager the new window never popup.

Alex

I have to generate simple graph at the run time which is based on couple of group and I have problem with it.

 

Here is the Data

 

Total	Year	Type
4	2009	Type1
1	2008	Type1
2	2008	Type2
3	2008	Type3

 

 

 So my X – axis will have Year and Y axis will be Total. I need to show Type for each Year. Since Type is missing for the Year 2009, I have seeing this issue.

 

 

My requirment

Am having 10 students in a class ,i will give fromdate and todate and get the attendence percentages of the students for the specified period.Now i want to show the barchart showing students name and attendence percentage in the bar,different colour for different percentages.

Am new to radcharts plz help me to find the solution.

We have a radGrid which is loaded many columns.

Each column’s wide is narrower so more columns can be displayed.

One of the columns has radCombo box as a drop down list, and the record count label text extended outside of the comboBox.

This looks very undesirable.

Here is a screen shoot http://lh4.ggpht.com/_ohpx5KZcsi0/SzDjYr35nHI/AAAAAAAAFHU/AH-wzDkTMBI/comboBoxOverlap.JPG

 

Can this problem be fixed?

The RadMenu is ignoring the SelectedCssClass property when using ItemTemplates. It is correctly applied if ItemTemplates are not used.

CSS:

Markup:

I have a line chart that has one Series of data.
Is there a way to add points to the line?
or taking it from a differant way....is there a way to add a connecting line to a Point chart?

Thanks.

I am using the auto-generated edit form on the grid and handling any errors in ItemInserted/ItemUpdated event. My question is - what is the proper way to display an error message inside the edit form? If that's not possible, do you have any sample code that would illustrate some other technique like display a popup or anything user friendly? Thank you.

PROJECT DESCRIPTION
This is an alternative way to handle [ENTER] key to perform insert/update operation inside a RadGrid FormTemplate (EditFormType="Template") within a Content Page (Master Page template). For unknown reason (probably the FormTemplate with customized insert/update and cancel button), I was unable to handle the [ENTER] key event so this is a possible solution:
