I have a gridview with a template filed which contains an embedded gridview, which may or may not contain any records. I want to be able to make the master gridview row a different color for those rows whose child gridview has records. My plan is to add a sqldatasource to the page that targets the child gridview table and during the master gridview RowDataBound event I would check to see if there are any records and apply the formatting accordingly.

I'm trying to prevent data from loading on the page when its needed.
Currently, I check the IsPostBack bool to prevent loading data in my user controls which allows the data to be loaded when the page is initially requested.
However, if my page fails validation and the page is sent back to the user with error messages, my user controls no longer have data in them because the initial request was a postback.
One solution is to have a flag in every user control (IsFailedPostBack) to force them to reload their data. Is there a better way?
I'm using a wizard control with 4 steps, when I use the previous button to navigate back to the previous step the page reloads but at the bottom of the page.Instead of showning the whole of the page, the user views the footer of the site and the previous button and next button.I'm sure there is a very simple answer to this but I just can't figure out how to get the page to reload to the top.
I have a page register.aspx that a user can use to register on my website. Once the registration process is completed, I redirect the user to thankyou.aspx where he will get a code to activate his account.
My problem is this: from the thankyou.aspx page, if the user click the "previous button" on the navigator, he can still have access to the information he had previously submitted and might cause data duplication . I don't want this to happen. I want in that case to redirect him back to thankyou.aspx or another page which will be different than the register.aspx.
My questions are:
1. how can I prevent the user to use the "previous button" on the navigator to avoid data duplication? 2. in case question 1 cannot be done, how can I know in register.aspx that the user comes from thankyou.aspx (which should not normally happen) so that I can redirect him to another page?
My approch was before redirecting to thankyou.aspx, I concatenated session.sessionID and another data to be retrieved on thankyou page. And on thankyou.aspx, I destroy the session after the page was loaded by using Session.Contents.RemoveAll(). And here, nothing happens. The session is still on when using the previous button.
I have a delete button bellow my gridview and I want a pop up to show when no record is selected and tell the user to first select a record. The button click event would show the pop up, but my gridview data blanks out.
I want users to select a record in the GridView and then have that record open up in the Detailsview. How would I go about getting these two tools to communicate?
I've an application in asp.net, and when i click on back button IE browser taking back to previous page,i want to prevent the user going back to previous form.if user try to going back to previous page a meesage pop-up should show saying "You cannot go back to previous page, you have to re-login to see the previous page".
i have design a web application having suppliers table using SqlDatasource..
i have a master page in my design and other form are bound to a context menu..
Now i have displayed the records in the gridview..all i wanted is after i select a record in the gridview it will display the selected record in detailview from another aspx form..
i was able to create the link to another aspx form but the data that it display is the first data from the gridview not the data that i select.
I am using a Gridview binded to a LinqDataSource that represents a database view. The gridview paging is enabled. When navigating from page 1 to page 2, it displays the right count of rows in this page (assume pagesize is 10 and page 2 should have 4 rows only to have total of 14 rows in the view; the datasource), however, it populates wrong data (from the previous page). On the contrary, when I disable paging, everything works ok.
I have a tab control with details about a user. I want to use javascript to change some visuals. It works fine if the control affected are not in the tab container, but as soon as I have the controls in the container it won't work as the tab control renames all it's child controls to something like this: <input name="TabContainer1$TabPanel1$Txt_Name" type="text" id="TabContainer1_TabPanel1_Txt_Name" />
It should be: <input name="Txt_Name" type="text" id="Txt_Name" />
Now my javascript won't work as it can't find the controls. I did try doing this: document.getElementById('<%= Txt_Make.ClientID %>') But then I this error "The Controls collection cannot be modified because the control contains code blocks (i.e.<% ... %>)."
I just need to know how to stop the Tab Container from renaiming the controls, please? I am still searching, but I'm also runnign out of time.

I'm new to ASP.net 3.5 and trying to create a test site so I can figure out how to use it in the real world. I have created a FormView (Formview1) based on a Client table using Linq Data Sources. The page includes a DropDownList to lookup Clients. I have added a list option (<asp:ListOption value="" Text="(Select Client)" and set AppendDataBoundItems=true so my added option is displayed. I decided to try to use Formview with only the Edit and Insert Modes, and I have set the Default Mode = Insert. When you open the page, a blank Client record is displayed.
The Client record contains serveral lookup fields and they have drop down lists for each. When I select a client from the Client DropDownList, is get the following message 'ddlClientType' has a SelectedValue which is invalid because it does not exist in the list of items I had this problem before and decided the best way to handle this (in the interim) was to turn off foreign key constraints for each of the lookup fields (e.g. ClientType) in SQL Server. That worked for 2-3 days. Now the problem has started again.
When I develop in other applications, I would simply create a lookup data source based on a Union Query with the actual data and a blank record. How can you do this using Linq DataSources. Can you get access and modify the queries?
I have a DataGrid bound to an ObjectDataSource, as you know once the DataSourceID on DataGrid is set, data binding happen automatically without any coding. But due to requests from end users, I need to prevent the data binding when the page is loaded the first time, i.e. data binding should only happen during PostBack. How do I do that?
I enable AutoGenerateEditButton = "true", which can show me edit button in the child grid. Also i have tried to use the event rowediting which can return e.NewEditIndex too. for the master i use sqlDatasource design time. for the child grid am confusing how to do the edit/delete/add.

for child grid datasource if am not mistaken, guess need to assign the datasource during runtime. am not sure how to do this?
I am currently trying to figure out the best way to handle a data formatting issue. I have a stored procedure that pulls back basically all the data I need, but using a gridview doesn't really give me what I need.
For example...currently the gridview displays data like:
I am having my first go at a nested gridview within a gridview. I have successfully loaded the data and it displays fine. Within the child gridview I have two textboxes that the customer can change. I also have an Save button. When the customer selects the save button the RowCommand for the child grid executes as it should. However I am unable to figure out how to access the two textboxes.
In the past I have got the row index from e.CommandArgument, established the correct GridViewRow using the gridview ID and the row index, and then used findcontrol to get the textbox
int index = Convert.ToInt32(e.CommandArgument); GridViewRow row = gvGridView.Rows[index]; TextBox txtName = row.FindControl("txtName") as TextBox;
But when working within the Child GridView RowCommand event I am unable to figure out how to gain access to the textbox. The child gridview is not recognized.
