View 4 RepliesI have got 2 Drop Down Lists on my Form and 1 GridView. I want GridView to display the data according to selection from the Drop Down Lists.
For Example, One Drop Down List contains Names and other contains Dates. Both the Drop Down Lists can post back. So if i select a name from 1st Drop Down list, the Grid View should show all the results according to that Name. Similarly if i select the Date from the other Drop Down List , the Grid View should show the results according to the dates. But i cant figure out as how to bind Grid View to respond to 2 Drop Down List.
BTW i am binding both the Drop Down Lists and the Grid View to the DataSource Objects, which is getting data from the database.
I have 2 grids gvParent & gvChild I would like to filter gvChild when a row is selected in gvParent the linking fields are contractNo
I added a column for selecting:
<asp:TemplateField ShowHeader="False">
<ItemTemplate>
<asp:LinkButton ID="LinkButton1" runat="server" CausesValidation="False" CommandName="Select"
OnClick="LinkButton1_Click" Text="Select"></asp:LinkButton>
</ItemTemplate>
</asp:TemplateField>
I know how to handle the filtering of the grid (create a criteria and set to rowfilter of the dataview) But, I dont know how to get the value of the column of the selected row.

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 am new to asp.net and was trying to use datagridview in my webform. I was able to bind it to my database but I cannot make the datagridview's buttonfield respond. It seems the grid's SelectedIndexChanged event is not being fired or has issues with postback. Even a very simple statement is not being executed by the program e.g.
protected void grid_SelectedIndexChanged(object sender, EventArgs e)
{
detailsLabel.Text = "asdfasdfsafasddf";
}
It seems the SelectedIndexChanged is not being fired. I have checked my IE and scripting is enabled.
I am using VS 2008 and IE7. Can anyone share a solution on how to solve this issue?

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.

how to reorder a datadrid, by moving one row up or down.
View 1 RepliesI notice that the DataGrid control has properties for "SelectedRow". What I don't understand is how to select one. Nothing looks clickable when I'm viewing my datagrid populated with data, it just looks like a static table of information.I need two things to happen. 1, as they move their cursor over the rows, I need the row to highlight. 2, when they click a row, I need to fire an event so I can run an SQL query based on the row they clicked?2 questions.1. Is it possible for a DataGrid to do this.2. If it's not possible, what should I be using instead?
View 20 RepliesI have a table in my database with three fields: COURSE_ID, PERC, DATE.I need to display sets of rows based on the date, the number of rows in every set will be known at run time, the same as the number of sets, so I was thinking about adding two buttons (one to add a set and another to add rows in that set)
I know that working with GridViews will do, but do not know how exactly, maybe one gridview for the sets and a second gridview (inside the first one) for the rows inside the sets.
<Add Set>
<Add Row>
Set 1
COURSE_ID PERC DATE
2 10 2010-12-02
3 90 2010-12-02
Set 2
COURSE_ID PERC DATE
3 90 2010-12-10
4 10 2010-12-10
Set 3

View 3 RepliesI 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

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...??
