View 6 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.

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.

View 2 RepliesIf i have a page which displays all the data but with only a few fields, then i select one of the data and then i want to be able to view that data with all the fields related to that data on another web page.
I have been able to view the data in Grid view and enable the Select, Update, Insert and Delete. But not able to use the select button to view the information on another web page.
I am new to asp.net. I have C# MVC application and I need read data (id, name) from .mdb file (in controller) and then pass it to view.
My controller code:
OleDbConnection con = new OleDbConnection("PROVIDER=Microsoft.Jet.OLEDB.4.0;DATA SOURCE=" + Server.MapPath("App_Data/data.mdb") + ";");
I am displaying selectable rows in a gridview. The selected row uses a stored procedure to display all the fields in a formview when the Select button is clicked.
Only a small subset of the fields in the selected row are editable. When I click the Edit button only the EditItemTemplate fields show up, the read-only fields from the ItemTemplate disappear. I want the read-only rows to remain visible with the editable rows.
If I include the read-only fields in the EditItemTemplate, I get an error when I click Update on the FormView. The error states that there are too many parameters being passed to the stored procedure to update fields. How can I continue to show the read-only fields with the editable fields on the FormView and avoid getting the input parameter error on the stored procedure for the Update command?

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.

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...??
