Hiding expand/collapse images when no records

[santhosh]

Hi,

I want to hide the expand/collapse images in hierarchical radgird when there are no records, i tried the method provided in the help link but that's not working for me it hides all the expand/collapse buttons independent of wheather the records is there or not.

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

I am building 3 levele hierarchical grid, manually i am building the tables and setting and binding the datasource at the server. kindly advise how to hide expand/collapse images in my case, Thanks in advance. below is my code.

This is the way iam setting and bindiing the datasoruce for the grid

RadGrid1.MasterTableView.DataSource = dtTable1

 

RadGrid1.MasterTableView.DetailTables(0).DataSource = dtTable2

RadGrid1.MasterTableView.DetailTables(0).DetailTables(0).DataSource = dtTable3

RadGrid1.DataBind()

The table structures are as below

 

dtTable1.Columns.Add(

"dt1Id")

 

dtTable1.Columns.Add(

"Type")

 

dtTable1.Columns.Add(

"Date")

 

dtTable1.Columns.Add(

"EmptyColumn")

 

dtTable1.Columns.Add(

"Description")

 

dtTable1.Columns.Add(

"Status")

 

dtTable2.Columns.Add(

"dt1Id")

 

dtTable2.Columns.Add(

"Type")

 

dtTable2.Columns.Add(

"Date")

 

dtTable2.Columns.Add(

"EmptyColumn")

 

dtTable2.Columns.Add(

"Description")

 

dtTable2.Columns.Add(

"Status")

 

dtTable3.Columns.Add(

"dt1Id")

 

dtTable3.Columns.Add(

"Type")

 

dtTable3.Columns.Add(

"Date")

 

dtTable3.Columns.Add(

"EmptyColumn")

 

dtTable3.Columns.Add(

"Description")

 

dtTable3.Columns.Add(

"Status")

Hi,

Try setting the HierarchyLoadMode property in the MasterTableView and the second level GridTableView  to ServerBind. Then the solution suggested in the preceding help topic should work.

I hope this help.
