[Solved] Filtering MasterTableView When RADGrid is binded to List Object

[Yuvika]

Hi,

Binding RADGrid to list object in general case scenario works good. But I have a situation where I am using the RADGrid for showing hierachical data and I am using self referencing telerik RADgrid grid. For the first level my parentFileID property has null value. so I want to filter my records for masterTableView with FileParentId.

The below code gives error when I bind the grid to a list object.

if

(Assembly.GetAssembly(typeof(ScriptManager)).FullName.IndexOf("3.5") != -1)

 

{

grdsearchresult.MasterTableView.FilterExpression =

@"it[""FileParentID""] = Convert.DBNull";

 

}

 

else

 

 

 

 

{

grdsearchresult.MasterTableView.FilterExpression =

"FileParentID IS NULL";

 

}

For Eg:

 

 

List

<SearchResult>  listSearchResults=new List<SearchResult>();

grdsearchresult.DataSource = listSearchResults;

 

grdsearchresult.DataBind();
Here my datasource is List Type Object.The grid shows all records if I dont filter it.
So While binding the master records I get error index is not defined.?
Can't I bind the RADGrid with list object and provide filter to it.

Please reply.
Thanks,
Yuvika

Hi Yuvika,

Can you try:

grdsearchresult.MasterTableView.FilterExpression = "FileParentID == null";

to see what will be the result?
