View 7 RepliesI 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?
View 3 RepliesI want to dynamically bind dataset values into datagrid's header datafield.
Is it possible? To be more clear, when you click on datagrid's (Collection) from properties window, you get selected columns created from Bound column. So in those columns I want to dynamically display dataset's table values in those columns.
i.e like ds.Tables[0].Rows[0][0].
Is it possible to do it in Datagrid ItemDataBound function like,
e.Item.Cells[1].Text = ds.Tables[0].Rows[0][0]
or something like this? I know the above code is wrong and wont work since I tried it out and while building it throwed error saying, Cannot implicitly convert type 'object' to 'string'.

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.

View 2 RepliesI 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.

I have a datagrid which pulls data from a single database table to display it. However, this database table also contains information on the thumbnail URL for each record, and I would like to display the thumbnails for each record in the 1st column of the datagrid.
At present I have added the following to my datagrid:

So I presume the main challenge now is to set the Thumbnail.ImageUrl property to the correct file path in the VB.NET code. But how do I do this for each record? I am using a function to retrieve data for the gridview, which is based on the following:

I am having an issue with a simple databind to a datagrid. What happens is that for some reason, the first character of the data going into the 4th column is getting placed at the end of the data in the third column; but only on the first row. Here is an example of what I mean:
Form ID
Employee No
Associate Name
Start Date
End Date
Form Status
1234
5000187

As you can see, in the first row of data, a "1" has been moved from the Start Date column to the Associate Name column. Because this is a databind I don't see how this is even possible. I'm just curious if this is a known issue or just some random fluke. Here is the relevant code:

I have a web application that takes information entered by the user and displays it in a few datagrids, that are located withing a multiview.
In order to enter a row to a datagrid the user enters some information and clicking on a button calls a function that adds the data to an arraylist, which is the source of the datagrid. In addition, every postback the data is binded to the datagrid.
It all works fine in the first time, but from the second row and on it enters only parts of the data and ignores the rest.
I am doing when the form loads up
DataGridViewComboBoxColumn ComboTextCol = new DataGridViewComboBoxColumn();
ComboTextCol.Headertext = "some";
ComboTextCol.DataSource = GetEmployees().Select(e => new { Name = e.LastName + " ," + e.FirstName, ID = e.EmployeeID }).ToList();
ComboTextCol.ValueMember = "ID";
ComboTextCol.DisplayMember = "Name";
datagrid.Columns.Insert(0,ComboTextCol);
I tried this too datagrid.Columns.Add(ComboTextCol). GetEmployees gives employee data I see the column but not the the data...??
I have an SP in backend that retreives multiple recordset/DataTable where each recordset/Datatable contains 10 records and 8 columns.
The Count of recordset/Datatable differs based on parameters.
The SP retreives Data in nearly 0.01 seconds.
I have been displaying the records by looping each Datatable and each record in DataGrid Template Control, this way the page loads very slowly.
Can some one please suggest me on how to display/Load the data more efficiently and faster in front end ASP.NET 2.0?
Can I perform some Multithreading to display records from different datatables?
I am familiar with populating a gridview with data. I am able to bind the Data pulled from the database into the gridview
gridview.DataSource = myDataTable;
gridview.Databound.
If I write the following code, teh gridview will no longer show the data
gridview.DataSource = null;
gridview.Databound.
My question is , I want to make the same thing with a user control that contain a gridview. when I use the user control in an aspx page, I am able to populate it with data, but when I try to make this code, the Datasource does not show, instead, I see .DV. So I tried this code but then , I do not see DataSource property instead I see DV (DataView), when I put .DV = null, I get an error message that the object is not in existed. any idea how to clear the user control gridview from its data.
