Hello All,

I have rad grid with one template column(of <asp:Label Id="lblTemplate" runat="server" />). In grid's ItemDataBoud event, I am assigning that
label's value using some other data source(not used by Grid).

Grid renders perfectly but inbuilt filtering is not working as I have not assign "DataField" property on "TemplateColumn". I couldn't do so because "DataField" is not available in Grid's data source but available in another data source which is I am using in ItemDataBound event.

What is best and efficient way to achieve my requirement?
If I need to use custom filtering then how can I do so?
Regards,
Dharmesh

Hi,
Presently iam using telerik Grid demo version.
Now for our project we are using Spread grid.
now we are in plan to migrate all our spread grid to Telerik grid control.
for this we are doing sample telerik grid with our same spread grid results.
now mostly we have done all major part of things
but in one gantt view development with pivot grid we are not able to produce the result same like our spread grid.
Please see the attached image we need same result using Telerik grid Pivot grid.
for example we need row field as Item name,Item No,
and Column Filed we need Schedule Start year/month,Week with date
and in Aggregarte field we have result type.
result type 1 = yello color
type 2 =green color
type 3 blue color
type 4 pink color
 How to get this using pivot grid .
Is any similar sample available If its so it will be very great full me us to shoe the demo to our dir and purchase the telerik controls for asp.net

Dear Team,

I Have attached  Sceen Shot for my problems.Give correct solutions or please progrmatical how to create this..give sample..code..
I give that Code Below..in detail bind..

    protected void rdReport_DetailTableDataBind(object source, Telerik.Web.UI.GridDetailTableDataBindEventArgs e)

        {

 

            GridDataItem dataItem = (GridDataItem)e.DetailTableView.ParentItem;

 

 

            #region Child

            string columnname = Session["ColumnNam"].ToString();

            string ReportId = Session["ReportId"].ToString();

            string mapping = Session["MappingField"].ToString();

            string Column = columnname.TrimEnd(',');

            string tablename = TableName(ReportId);

            #endregion

 

            #region SubChild

            string ChildColumnName = Session["ChildColumnNam"].ToString();

            string ChildReportId = Session["ChildReport_Id"].ToString();

            string ChildMapping = Session["ChildMapping_Field"].ToString();

            string ChildColumn = ChildColumnName.TrimEnd(',');

            string Childtablename = TableName(ChildReportId);

            #endregion

 

switch (e.DetailTableView.Name)

            {

                case "Child":

                    {

                        string DataKeyNames = dataItem.GetDataKeyValue(mapping).ToString();

                        string query = "select " + Column + " from [" + tablename + "] WHERE " + mapping + " ='" + DataKeyNames + "'";

                        e.DetailTableView.DataSource = GetDataTable(query);

                        break;

                    }

                case "SubChild":

                    {

                        string Query = "select " + ChildColumn + " from [" + Childtablename + "] WHERE " + ChildMapping + " = '" + dataItem[ChildMapping].Text + "'";

                        e.DetailTableView.DataSource = GetDataTable(Query);

                        break;

                    }

            }

}

Hi guys,

This is a very simple to reproduce issue for us, but may be almost impossible for anyone else to reproduce due to the complexity of the page its happening on.

First, the simple part. We have a page which contains a RadTabStrip and RadMultiPage, with about a dozen tabs each with their own user control.

On the 2nd tab is a RadGrid which has a User Control Edit Form that contains multiple controls, including 2 RadDatePicker's.

So long as there is a date assigned to those RadDatePickers all is well. The minute we assign the value "null" to one of them, all of a sudden we cannot click on that tab - clicking on it does nothing. In fact, none of the tabs work at that point. We move the null value back to a datetime value, and poof - it works again.

I have tried every iteration I can think of to set the date to null, like using the RadDatePicker.Clear() method, using the DBSelectedDate and setting it to either null or DBNull.Value, or just setting the SelectedDate to null. All of which cause the side effect of the radTabStrip breaking.

Now... Just for giggles I did a View Source on the rendered page when it worked and again when it did not, and ran those sources thru WinMerge to see the differences. 

Of course the Viewstate was different, as was the Event Validation collection as would be expected. 

The rendered tables for the RadDatePicker objects had minor changes as well (Value="1/1/1990" vs Value="")

That would not cause any issues. 

The one that proves interesting is at the bottom of the rendered code. These 2 lines were different:

$create(Telerik.Web.UI.RadDialogOpener ...<truncated>
$create(Telerik.Web.UI.RadEditor, ...<truncated>

Now... That I think is where the problem is happening... but I'm stumped as to why, so I thought I would add both bits of code here to see if a Telerik expert sees something I'm missing.

First, this is the code that works - tabs open with no issue:


Both those functions are "different" between that (working) copy, and the following non-working copy:


Any help on this would be greatly appreciated... its got me stumped!

Thanks,

Dave

Hello,
   Depending on what node the user clicks, I would like to disable/hide a certain RadMenuItem. 
I found this
http://demos.telerik.com/aspnet-ajax/treeview/examples/functionality/contextmenu/defaultcs.aspx
but need to find out if a node has siblings.

thanks

Hi,
I want to hide my expand/collapse button of Column header in Rad Pivot Grid

hi,
I like to share my telerik Grid Helper class.
user can use this class to create there telerik grid by coding.
1) The Helper class for telerik grid,
I have created comman function like layout,page setting,client setting,data bind,master table setting,Image column,bound column,template column (Texxt box,link button,numerik text box,search box,lable),button column,

2) Simple ASpx design which has client event.here i used placeholdre where the radgrid will be added.This has header check box select all function.

3) CS file here you can see the actual code to call the helper class and data bindings .for more details see the code details.
