I have a gridview which i bind to DataView. I need to manipulate text on cell[2] of each row. I was wondering if i could do it in the OnRowCreated event? cell[0] in asp looks like this
<asp:ButtonField DataTextField = "header" CommandName="select" HeaderText="Overskrift"/>
This doesnt work. test = null
protected void onrowcreated(object sender, GridViewRowEventArgs e)
{
TableCellCollection cells = e.Row.Cells;
string test = cells[2].Text;
}

View 2 RepliesI'm having a weird problem where the GridView cell that I'm programmatically updating turns grey, and throws a null error when attempting to save row. I have been searching all day and have not been able to find a solution. I'm guessing there is a problem with my code, so here it is:

How to set Height and ItemSource(Business Object as DataSource for Cell) for every Cell in DataGrid/ Grid? Shown below is part of code I am currently using with Grid Control. What I am currently doing is that I am using ListBoxItem, set Item Height and ItemSource at ListBoxItem Level, Add ListBoxitem to ListBox and then Add ListBox to Grid, It leaves me with just one row and multiple columns in the Grid, which is perhaps not the best way of doing it as it doesn't allow me to take benefits from UI Virtualization of Grid.
[code]....
I am open to use any control i.e. Grid/ DataGrid provided it allows me to set Cell Height and item source at Cell level. In my requirement, Cell height depends on the Item duration and size of image, which means the height of the cells may not be same across cells in any particular row.
I had a problem for a long time but now wonder how I will solve this. Perheps it is easy.
I have a <table> with two <td>. This <table> resides inside a GridView, so I FindControl like below. Now I need to do a calculation of height that if MessageBox1 have a height that is less than 306, then I need the MessageBox2 to have the remaining height.
For example if MessageBox1 has the height of 206, then MessageBox2 need to have the height of 100.
I think my problem is how to convert the height of MessageBox1 correctly and set the remaining height to MessageBox2 ?

I´m trying to link the gridview to detailsview and I used this page as my inspiration:
http://quickstarts.asp.net/QuickStartv20/aspnet/doc/ctrlref/data/detailsview.aspx
But I´m trying to do that programmatically, not with the sqldatasource. So I wrote the method that binds data to Detailsview and I call it in the page_load. The problem is that I have to click two times on the select button to view the detailsview. The first time I click on the select button nothing happens.
I have a gridview with a Select button. Clicking the Select button for a particular item, I need its full details displayed in DetailsView. how I can bind to DetailsView? Here is what I have so far.
.aspx
<asp:GridView ID="GridView1" runat="server" AllowSorting="True" AllowPaging="True" PageSize="10" OnPageIndexChanging="countryGrid_PageIndexChanging"
CellPadding="4" ForeColor="#333333" Width="400px" Font-Size="9pt" [code].....
I have ImageButton into DetailsView i use it in delete, I need to get on value cell ID to use this value in delete command in GridView i was using command like below code ... but i don't know How the situation of DetailsView.
Code:
int x;
x = GridView1.SelectedIndex = ((GridViewRow)((ImageButton)sender).Parent.Parent).DataItemIndex;
string ID = GridView1.Rows[x].Cells[0].Text;
I have a detailsView whose date values in a cell are currently being displayed in longDateFormat, i want to convert all date values in this DetailsView to short date.
For example, instead of 6/1/2010 12:00:00 AM, i want to display just 6/1/2010
For a Gridview, i can achieve that by the code blow
Protected Sub DetailsView4_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles DetailsView4.DataBound
If e.Row.RowType = DataControlRowType.DataRow Then
For i As Integer = 0 To e.Row.Cells.Count - 1
Dim cellDate As Date
If Date.TryParse(e.Row.Cells(i).Text, cellDate) Then
e.Row.Cells(i).Text = String.Format("{0:d}", cellDate)
End If
Next
End If
End Sub
How can achieve the same with a DetailsView?
I have a DetailsView Control, inside as a template a TextBox. I need to findout the value for a TextBox when Inserting data Event handler-, _ItemInserting. The script does not work.
<asp:TemplateField HeaderText="Profile" SortExpression="ContentAuthor">
<ItemTemplate>
<asp:Label ID="uxContentAuthorDisplayer" runat="server" Text='<%# Bind("ContentAuthor") %>'></asp:Label>
</ItemTemplate>
<InsertItemTemplate>
<asp:TextBox ID="uxContentAuthorInput" runat="server" Text='<%# Bind("ContentAuthor") %>'></asp:TextBox>
</InsertItemTemplate>
</asp:TemplateField>
CODE BEHIND
protected void uxInsertAuthor_ItemInserting(object sender, DetailsViewInsertEventArgs e)
{
//// Find control on page
TextBox myAuthorProfile = (TextBox)uxInsertAuthorInput.FindControl("uxContentAuthorDisplayer");
// Set a default value in Data Base if field has been left empty (DB field NOT NULL)
if (string.IsNullOrEmpty(myAuthorProfile.Text))
{
string myAllert = "Field is NULL";
}
else
{
string myAllet = "Field is NOT NULL";
}
}
how to retrieve the selected row cell value if it is visible property is false in gridview?
View 1 RepliesI have been struggling with DetailsView for quite some time.
Only chkActive and txtStatement in the code below are Editable. So when I click Edit, edit the fields and click Update, it does go to the ItemUpdating event, but I'm not being able to retrieve the updated values.
I get error-

I have a column that I don't want to display but I still want to access its value. the other problem is that I can't access the value of a cell because it contains a label. Does someone know how to access the text in that label?
View 3 RepliesI'm using a detailsview control to update a record, however in this particular case there's only one field that can be changed out of a many. The update method for my object takes all fields as parameters. When the detailsview's updating method fires, the values for the readonly fields (those rendered as a Label) are not available in the e.NewValues collection.
I'm currently grabbing a reference to the object when the detailsview is databound (in the objectdatasource selected event handler), storing it in session and manually adding entries to the e.NewValues collection when updating fires. It works but seems kind of heavy handed. So, is there a better way to get the read only values back into my update method? Or is there a better way of doing this altogether?
this item colum called Id.
rowItem.Cells[0].FindControl("Label1").ToString();
it insert my to the db this value:
System.Web.UI.WebControls.DataControlFieldCell

I am trying to debug one of the project in which i need to show the data for one of the particular cell in two lines.
