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:
Date1 ProjectCode1 Hours ApproveChkBox
Date1 ProjectCode2 Hours ApproveChkBox
Date1 ProjectCode3 Hours ApproveChkBox
Date2 ProjectCode1 Hours ApproveChkBox
...
I would like to be able to display the information like:

Is there anyway to do this using a nested gridview? Or is there a proper way to display this type of format?
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.
I have a requirement where I need to show the data in parent/child form .For Example - Lets says we have have customers and each customers can have multiple orders.I need to display it like this -
Cust1
Info about the customer
Gridview (showing all the orders for the cust1)
Cust2
Info about the customer
Gridview (showing all the orders for the cust2)
What controls should I used

I have some data which contains angle brackets in some of the fields.Even if properly escaped as <: or > (or even the hex codes), or contained in CDATA, in Visual Studio 2005 ASP.Net, the field data is being truncated at the first angle bracket. If I replace the data with curly braces, it displays fine.Is this a parser defect in the TreeView control? I can use Response.Write and see that the data provided by the XmlDataSource is fine. Example:
<ITReview>
<row TopNode="REQ 123456 TT Description <Date sent to app dev> <Priority> <SubTask Status>"/><row TopNode="REQ 456789 TT Description <Date sent to app dev> <Priority> <SubTask Status>"/>
</ITReview>
<ITReview>
<row TopNode="REQ 123456 TT Description <Date sent to app dev> <Priority> <SubTask Status>"/><row TopNode="REQ 456789 TT Description <Date sent to app dev> <Priority> <SubTask Status>"/>
</ITReview>
This truncates right after TT Description. If I change to curly braces or parentheses, it displays fine.
I have an excel sheet which has several parent records/rows and every parent row/record has several child sub-records under it. I have a field called ID which is of the type String as it contains a mixture of characters and numbers and is common for both parent and child records. How do I store the parent and child records in separate database tables, retrieve them and display them in a nested gridview?
View 1 Replies I have nested gridviews, in the outer grid I am displaying the question and in the inner grid 4 options are displayed in radiobuttons. I have kept Lock Answer button inside Item Template in inner gridview , so this button is coming with each and every question and when i click on Lock Answer button in front of any question, its saving the corresponding answer in the database. For ex, if there are 10 questions this button is coming with all the questions, all the questions are on single page and all are multiple choice. Now everything is working mine, my requirement is that I need on 1 common Lock Answer button at the bottom of the page and not with all the questions. And when I click on that common button it should run for all the questions that are displayed on the screen at should fetch and update each unique answer corresponding to that question in the database. Below is my code:
<asp:GridView ID="gvouter" runat="server" GridLines="None" AutoGenerateColumns="False"
AllowPaging="false" OnRowDataBound="gvouter_RowDataBound" Width="100%" OnRowCommand="gvouter_RowCommand"
OnPageIndexChanging="gvouter_PageIndexChanging" >
<PagerSettings Position="Top" />
<Columns>
<asp:TemplateField>
<ItemTemplate>
