I am having one RadGrid and binding one Datatable to it From codebehind.
At each paging or sorting or drag drop column it goes server side (page refreshed) and then displays.
is there any professional way i can achieve this with faster speed.
my code is

<telerik:RadGrid ID="RadGridEmployeeCost" runat="server" AllowSorting="True" AllowPaging="true"

AllowFilteringByColumn="true" CellSpacing="0" GridLines="None" HeaderStyle-Font-Bold="true"

Skin="Web20" OnNeedDataSource="RadGridEmployeeCost_NeedDataSource" ShowGroupPanel="true"

OnColumnCreated="RadGridEmployeeCost_ColumnCreated">

<ClientSettings AllowDragToGroup="True" />

</telerik:RadGrid>

AND

protected void RadGridEmployeeCost_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)

{

ObjCon.Open();

SqlCommand ObjCmd = new SqlCommand("SELECT name,address,TelPhone,EmailId,Qualification FROM WorkSummary", ObjCon);

ObjCmd.ExecuteNonQuery();

SqlDataAdapter ObjDa = new SqlDataAdapter(ObjCmd);

DataSet ds = new DataSet();

ObjDa.Fill(ds);

RadGridEmployeeCost.DataSource = ds;

}

protected void RadGridEmployeeCost_ColumnCreated(object sender, GridColumnCreatedEventArgs e)

{

if ((e.Column is GridBoundColumn && e.Column.UniqueName == "TelPhone" || e.Column.UniqueName == "EmailId" || e.Column.UniqueName == "Qualification"))

{

GridBoundColumn column = e.Column as GridBoundColumn;

column.AllowFiltering = false;

}

Dynamically show/hide Column Editor controls in row in edit mode based on data in the row?

In each row of a grid with EditType = "Row", I'm trying to show/hide the column editor controls based on data in that row. When some rows are in edit mode (after being clicked on), they will display a text box, checkbox, etc. approporiate for that particular row. Other rows will hide that option in the same column.
For the entire column, edit controls can be shown/hidden based on the column's ReadOnly field. Can this be turned on/off for individual rows?
Would prefer to handle this server-side. Trying to avoid managing dynamically added controls based on data conditions and instead simply turn on/off editing in specific cells of each row.

In the example below, when a row is in edit mode, I want the edit text box in the MilkType column to only display if the Product for that row is Milk. Otherwise the cell should be read-only when the row is in edit mode.

Thanks!

EditForm problem - other rows display incorrectly when editing/inserting a record

I am trying to create a custom EditForm for use with the RadGrid. When I edit or insert a record, the other records in the grid display incorrectly.

My app:
- simple ASP.NET 4.5 web application
- OS: Windows 8.1
- IDE: VS2013.
- Telerik version - I am a consultant and using the DLLs provided by my client, so I don't have any sort of Telerik SDK installed. The version of Telerik.Web.UI.dll I am using is 2013.1.417.35 (17MB, dated 5/12/2014 7:50pm).
- Browser: Google Chrome Version 36.0.1985.125 m. I also tested on IE 11 11.0.9600.17207 (Update version 11.0.10).

}

I have attached three files:
- Pic1.png: Viewing the data (works fine)
- Pic2.png: Edit the "David" record
- Pic3.png: Insert a new record

I tried viewing source after clicking Insert, but it appears that source in that case is simply the source I see when I view the data. The custom edit form controls don't appear in that source.

Note that this is the same behavior as in this post:

Floating Column Chart

Hi there,

I am wondering if there is any support for a floating column chart. I tried to make my own by creating a Series with a white background, however, the column itself has a gray border.

protected void RadGrid1_UpdateCommand(object source, Telerik.Web.UI.GridCommandEventArgs e)

{

GridEditableItem editedItem = e.Item as GridEditableItem;

DropDownList list = editedItem.FindControl("DropDownListQUestionType") as DropDownList;

Session["updatedValueQUestionType"] = list.SelectedValue;

}

When I run the code I see the dropdownlist and it has data and it shows the correct drop down value when displayed.
On the RadGrid1_UpdateCommand it does see the value to hold it in the session but for some reason it actauly saves it back as a blank string.

Retaining checkbox selection server side on a radgrid using advanced data binding

Hi,

I was hoping to keep any ticked check boxes ticked when my radgrid rebinds. I found this tutorial: http://www.telerik.com/help/aspnet-ajax/grid-selecting-row-with-checkbox-server-side.html however my "onCheckedItem" events never fire, instead my "needDataSource" event is fired and that is the end of it (I verified this using debug mode and checkpoints). I'm assuming this is because I'm using advanced data binding unlike in the tutorial. I need to keep advanced data binding for features such as grid export. Also it's important the checkboxes are server side because I want to be able to build functions in c# which rely on what tick boxes are selected. Below is the code for my radgrid

Let me know if you need any more code. Thanks in advance

Can a radgrid bound to webservice use autogenerated edit form?

I created a radgrid bound to a webservice (by using ClientSettings/DataBinding). and found that I could not get the grid to go into edit mode at all. I wanted to have a grid with an edit button column, and simply click the button to popup an autogenerated edit form for that grid row, but it doesn't even attempt to open the popup or go into edit mode.

I tried a simple project where I set up a radgrid bound using another method (needdatasource) and set up the editing how I wanted it, and it all worked. But when I add markup for databinding the edit mode completely stops working.

Am I trying to achieve something impossible?
