View 1 Repliesi have a DatagridView which contains 5 columns. The Fifth Column can contain a number or a NULL value .
I need to edit the DataGrid it in such a way that the fifth column is hidden everytime.
And on a specific condition that if fifth column is not null , then display the value which is present in fifth column ,in a small subscript below the the corresponding element in first column .
I have a data grid and inside that datagrid check box and created using template field.
How can I check that a row in datagrid (not grid view) is checked or not.
For gridview we can use the below in codbehind file,
Boolean isChecked = ((CheckBox)(Row.FindControl("chkDelete"))).Checked;
For datagrid how to achieve this...
My aspx code is
<asp:DataGrid ID="dg1" runat="server">
<Columns>
<asp:TemplateColumn HeaderText="select">
<ItemTemplate>
<asp:CheckBox runat="server" ID="chkD" />
</ItemTemplate>
</asp:TemplateColumn>
</Columns>
</asp:DataGrid>
I just want a function which exports the table in the datagrid view into a text file or excel file on button click.

I would like the selectedvalue of the dropdown to display additional data base on its selection in multiple text boxes.
I have tried using the DropDownList OnSelectedIndexChanged property, within a DataGrid EditiItemTemplate, but I cannot retrieve data from the selection. (AutoPostBack is "True"). I can however use a button onclick event to fire a "prre-defined" selection value.
I have a datagridview control that I'm using to display cache data to the end used on a web form. The issue that I'm having is that every time I re-run the application, and the cache data is re-generated... it loads duplicate data that's being displayed to the end user. I can't seem to figure out how to keep this from happening.
What I would like to have happen is that only unique data rows be returned and cached for the end user. Unless there are new data rows on the database that needs to be included in the cache data results...the previous data results should not be duplicated. I've tried to change a few properties on the datagridview control, but nothing seem to keep this from happening.

View 2 RepliesI have this problem with DataGrid printing.
I have a page which contains somo labels and a DataGrid.
When i try to print the page, only 1st page contains the verticle and horizontal lines of the grid. The rest of the pages do not contain any lines.
Second thing, between pages while printing there are some word break of a line. I dont want this line break.
Here is the hyperlink control to my details page:

However, the details page could not retrieve the page base on the clsNotesID. Here is my SqlDataSource control:

The clsNoteID has a DataType of uniqueidentifier. I was wondering if the clsNoteID passing through the QueryingString has to be suround by a single quotes. If so, how do implement the single into my HyperLink control?
I need to read data in DataGridView from one page to display using label in Other Page.I think here using QueryString concept. i cant remember the coding for QueryString and How to get Query string in another web page.Please give the sample coding using C# for me.
View 4 RepliesI didn't had any problem using datagrid to display Sql table on ASP.NET page,
but as the table grows so as the datagrid, and now the item list is too long for one page.
So I would like to break the datagrid into several pages with page numbers. ( <1,2,3,4> click the number to go to next page)

I'm having troubles remembering how to grab the list view's state, or page, so that when you leave the list, you can return to the list view page you left on. I have a data pager, and I have hyplerlinks for items in the list view that take you to a file upload or file delete page, and then returns to the list view. It returns to the list view's initial state (first page).
View 1 RepliesI have followed an online Microsoft tutorial that walks through building a Northwind.xsd that includes ProductsTableAdapter and a few other such table adapters (http://msdn.microsoft.com/en-us/library/aa581776.aspx).
Question: I now see a update column at the start of each row of the datagrid for AllProducts page. When I click update on a row and change the value of one of the non-primary fields (ex. Productname) and press Update, I get the following error:
The GridView 'GridView1' fired event RowUpdating which wasn't handled. How do I implement this event handler in VB? I know that when I implement using SQLConnection and use templatefields to bind each column I don't need to implement each event handler.

View 3 RepliesThis morning I posted a question w.r.t Radio Buttons, but the requirement changed so I'm posing a similar question.
I want to have a checkbox in a datagrid.
Suppose I click on one of the checkboxes and then realize i need to click on another, the screen has to automatically uncheck the previously clicked checkbox and then check the newly clicked checkbox.
In other words I need to clear previously checked checkboxes and check the recently clicked checkbox.
Also, I need to update a label in the page with a value associated with the row of the checked checkbox.
I should not be using a javascript to do this.
