Hello

i have used <telerik:GridTemplateColumn> for each column in RadGrid... and have some issues like
1). Though i have provided width value to each column, there is no effect shown. when i used TableLayout="Fixed", each column is shown with provided width but rows' height are not looking proper. so is anyone let me know how to set individual column width?
2). i don't want horizontal lines between two rows. how to make it disable?
3). Though i set AllowPaging="True" and PageSize="20" and there are total 50 records as a result, than why its not showing paging?

thank you
Kamini

Hello Kamoni,

1. In order to set column width, set TableLayout as "Fixed" and then set HeaderStyle Width for each column.

2. You can hide the horizontal grid lines by using custom CSS which overrides default skin or create a custom skin that matches your requirement. Please refer the following forum which describes similar kind of scenario.
GridLines in Radgrid

3. Check whether you have set different PageSize in RadGrid and MasterTableView. This may be the reason for not showing paging in grid.

Hope this information helps,
Princy.

Hello Kamini,

Make sure you are data binding the RadGrid control correctly.

Hi Kamini,

You are causing an endless loop - you can't set a new pagesize in the PageSizeChanged event. Why do you want to do that?

You can fix the headers by setting UseStaticHeaders="true" in ClientSettings -> Scrolling.

thank you Dimo

yes, i came to know that i am causing an endless loop by using PageSizeChanged event when i debug code. then what is the solution of this problem.. if i remove PageSizeChanged event and changing page size from the dropdown beside paging, grid gets disappear.

thank you

Hello Kamini,

It will be easier for us to help you if you provide a sample page showing your current RadGrid configuration.

Hi Kamini,

Your RadGrid declaration and the paging works correctly on my side. Below is my test page using the NorthWind database. By the way, I am surprised that the DataSourceID for RadGrid is SqlDataSource7, while the ID of the SqlDataSource control is SqlDataSource10.

Hello

ohh i am so sorry.. by mistake i hv paste SqlDataSource10. actually in my code, grid is bind from code behind. n now page size changing is working but the Next and Previous buttons do not work. i have also tried EnableViewState="true". but stril its not working.
i m getting an error: "Invalid postback or callback argument.  Event validation is enabled using <pages enableEventValidation="true"/>"

string strSQL="SELECT CustID, CustName, DOBDate, CompanyName, Designation, Address, City, State, Zipcode, EmailID FROM CustomerID";

SqlDataSource7.SelectCommand = strSQL;

RadGrid1.DataBind();

Hello Kamini,

Why are you using declarative datasource (DataSourceID="..") and simple data binding in Page_Load at the same time? You should use only one of these techniques - in your case, preferrably declarative datasource, because paging is not supported automatically with simple databinding.

Please make sure you read and understand all the information provided in the following help articles:

http://www.telerik.com/help/aspnet-ajax/grdsimpledatabinding.html

http://www.telerik.com/help/aspnet-ajax/grdadvanceddatabinding.html

http://www.telerik.com/help/aspnet-ajax/grddeclarativedatasource.html

Also, remove the PageIndexChanged event handler, as it causes an infinite loop.

I recommend you to inspect our paging-related online demos as well.

http://demos.telerik.com/aspnet-ajax/grid/examples/generalfeatures/paging/defaultcs.aspx

thank you Dimo

my problem is solved.  now i come to know where i was stuck. i was binding Grid on BindGrid() function that was wrong. Because on NeedDataSource event, RadGrid can automatically be bind.

thank you again.
