I have two tables: First table called MainDataTable which has 3 columns: id, queryId (FK from DetailedDataTable table), details

Second table called DetailedDataTable which has 3 columns : queryId, Name, Query

Now on page MainDataPage.aspx I have GridView named gridview1 which is showing MainDataTable table values. When I click on 'details' column link (I took that as a Itemtemplate Hyperlink) it goes to new page called DetailedDataPage.aspx which is having new GridView gridview2.

Now gridview2 has to show output which will come from query which is stored into DetailedDataTable table in Query column

for example.

MainDataTable
id queryId details
1 5 select company (this is itemtemplate taken as a Hyperlink)

When I click on above Hyperlink It is going on DetailedDataPage which is having gridview2 and data coming on gridview2 is running Query column from DetailedDataTable

DetailedDataTable
queryId Name Query
5 Mycom select companyname from CompantTable

Now I want to run select companyname from CompantTable and show this output to gridview2 when i click on select company (this is itemtemplate taken as a Hyperlink) from MainDataTable .

Follow the Steps below...

1. First Fill the Grid of the page MainDataPage.aspx, In this Grid Pass the Id Of MainDataTable with the Navigate Url.
2. Make a Stored Proc to Select the Query that you have already stored in DetailedDataTable

that may look like

SQL

CREATE PROC [dbo].[SP_SelectQuery] 
    @Id INT
AS
BEGIN
    DECLARE @eQuery NVARCHAR(MAX)
    SET @eQuery=(SELECT Query FROM dbo.DetailedDataTable DDT INNER JOIN dbo.MainDataTable MDT ON
    DDT.QueryId=MDT.QueryId WHERE MDT.Id=@Id)
    EXEC(@eQuery)

END
GO

3. In DetailedDataPage.aspx take another grid and fill that grid with the above written stored proc by passing the Id value that you have given in Navigate Url of First MainDataPage.aspx.

Hope this would help you.
