Here is the scenario of my problem:
I have a default.aspx page which has two gridview controls i.e. Gridview1 [Displaying Order table] and Gridview2 [displaying OrderDetails table], when I am deleting a row in GridView1, GridView2 should also update its datasource because of referential integrity constraints.
Following is what I am trying to do in GridView2_Load event:
[Code]....
[Code]....
I have a gridview1 with a Select column, which has a SqlDataSource that executes a Store Procedure.
I also have another gridview2, which also has its own SqlDataSource, but in this case, the Store Procedure has a parameter. This DataSource assigns as parameter the gridview1 control, and its PropertyName is SelectedValue. How can I load the gridview2 when gridview1 is clicked in the Select Column?
I have a dropdownlist (ddlList) in gridview1. I need to reference that ddlList as my ControlID for the parameter.
I tried to define gridview1.ddlList, but this did not work. Is there any way (non-codebehind) that I can use to reference a dropdownlist which resides in gridview1 from gridview2?
I have 2 Gridviews of the same structure and header. I want when user click hear of Gridview 1 for sorting, the same sorting applies to Gridview2 onclick.

I have a Gridview, lets call it GVDistinctDate which displays Distinct Date in one column only. For example: I got 5 rows, and 1 column where the column only display distinct dates such as 02/04/2010 | 03/04/2010 | 04/04/2010 | 05/04/2010 | 06/04/2010 where obviously this dates come from a table in the database.
Now i want to take those dates in GVDistinctDate and assign it to another gridview, lets call it GVReport, as column Header Text. For this GVReport, the first column would be StudentID where a list of studentid will be displayed, and then starting from the second column onwards, where the Header Text would be the dates from GVDistinctDate, will display a Status of absent or present according to the studentID and the corresponding date. How do it get the dates from GVDistinctDate into the column Header Text of GVReport?
AND how do it display the Present or Absent status based on the studentID in column 1 GVReport and the dates on the Header Text? Below are the codes of how i got the distinct date into GVDistinctDate
[Code]....
The code below is for GVReport and the comments are where i tried to put in the dates into the column header text.
[Code]....
There is a problem here: GVReport.Columns(k).HeaderText = headerText
Error:Index was out of range. Must be non-negative and less than the size of the collection.

i have gridview in page and i want user see gridview2 to click on special data in column1 and user see gridview3 to click on special data in column2(gridview2 or gridview3 in everytime)
i use templateFiled for display gridview2 but when i want to display gridview3(with another templateField) , dont happen in gridview,
(I want to display nested gridview in GridView1 but GridView2 Or gridView3 by clicking on Column1 or column2)
Objective:
Have the MultiView1 display only if Frieght values exceed 15.50. If check box is checked, retreive the row values of the Gridview1 and Gridview2 to perform a task.There will be two check boxes. One will be conditionally hidden. Each check box has a different function.

I started a C# web project in Visual Web Developer. I dropped a grid view in with designer and connected to my remote SQL database with the designer dialog based wizard. All is well there. I have in my program also a textbox where a user enters a zip code and clicks a button 'search'. When the user clicks search I want to run the SQL command "select * from flat_list where zipcode='userszipcode'". In other words the userszipcode is dynamic and different every time. It is my understanding I should use a SQLDataSource object but I do not know how.

I have a problem to write a string to a LinkButton that is located inside a GridView1. Now the hiarchy of controls is like this to understand how to Find this control:
TabContainer0 TabPanel5 TabContainer1 TabPanel7 Panel8 GridView1 LinkButton1 So LinkButton1 that we want to write a string to is located in a GridView1 which is located in Panel8 which is located in TabPanel7 that is located in TabContainer1 that is located in TapPanel5 that is located in TabContainer0.
So below is my code but no string is written to that linkButton, so I wonder if I miss something basic out here?
