Footer Text In Datagrid Don't Apply The Changes In Code Behind?
Dec 29, 2010
I have a datagrid with a text footer, and wanted to change the text in this footer when change selection in dropdownlist, but this change is not visible on the client(browser). I've been doing some tests and if i use the databinding() method datagrid is updated, and the text is correct.
My question is how to force the table to be drawn with the new changes. I think what the databinding() method is redrawing the datagrid, in the browser.

Quick VS2010 question.
I tried to apply formatting to my text (tools>options>texteditor>htmlformatting>tags)
where you can change color, style, and font-weight of certain tags, I apply them, but they do not change the text editor rendering of these tags.
Anyone else tried this with no effect?
Otherwise it works ok, but I find it easier to use one color for html, one for asp, and one for ajax tags for my purposes.

I'm building a gridview on the fly in code behind:
[Code]....
I display the incrementing number in the header. I create a column to show the current Row Number, but I'm not sure how to display the header text (Incrementing number) in the corresponding footer. Is there a special trick for it if I'm creating columns on the fly?

I am trying to implement adding a new record using the Gridview footer.
I have an example that works finethat I got from [URL]
My situation is a little different .. as I am using master page and the Gridview is in a page derived from the master page.
I have tried:
Dim txtNewName As TextBox = DirectCast(GridView1.FooterRow.FindControl("NewName"), TextBox)
"NewName" is the ID of the textbox in the footer of the Gridview.
When I try referencing ... txtNewName.Text ... it returns a null value.
There must be some trick to referencing this .Text value when using the Gridview that is within a Content Place Holder that results when using a page that was created using a master page.

i want to display a multiline text in a datagrid
i try with a textbox and with a label but with the textbox
<asp:textbox ID="textbox1" runat="server" style="overflow:hidden" Font-Size="15px" BackColor="#FFFFC0" TextMode="multiline" Width="750px" Wrap="true" borderstyle="None" BorderWidth="0" Text='<%# Databinder.Eval(Container.Dataitem,"text_caption") %>'></asp:textbox>
i receive only the first two lines
and with the label
<asp:Label ID="Label112" runat="server" BorderStyle="None" Width="750px" BorderWidth="0" Text=' <%# Databinder.Eval(Container.Dataitem,"text_caption") .ToString.Replace(chr(13),"<br />") & "<br/>" & "<br/>" %>' ></asp:Label>
if the text is too big without an enter then the datagrid width becomes too big although the text is diplayed normal with new lines
the textbox that i use to insert new text is here
<asp:TextBox ID="tbox_text_caption" runat="server" Height="232px"
Style="left: 400px; position: absolute; top: 8px" MaxLength="750" TextMode="MultiLine" Width="752px"

I just wrote an application level err handler for my website. The errors are saved in sql server. Now I download the info back into a datagrid and on the selectedrow changed I put the stacktrace and other big fields in textboxes like so :
[Code]....
However the text is now formatted like this :
txtSearchClient = ""
instead of :
txtSearchClient = "";
I've confirmed that the text is in the right format in SQL server but I cna't find a way to deencode it.

I have a DataGrid defined with columns such as:
Code:
<asp:BoundColumn HeaderStyle-HorizontalAlign="Center" ItemStyle-Width="10%" DataField="MONTH_PREVIOUS_YEAR" HeaderText="Month Hours (Previous Year)" ItemStyle-HorizontalAlign="Right"></asp:BoundColumn>
At a certain point in my program, I successfully re-set some of the Header titles programmatically:
Code:
Private Sub dgAccountability_ItemDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.DataGridItemEventArgs) Handles dgAccountability.ItemDataBound
If e.Item.ItemType = ListItemType.Header Then
Dim previousYear As Integer = (Integer.Parse(year) - 1)
e.Item.Cells(1).Text = "YTD Hours " & previousYear.ToString

i want to display a multiline text in a datagrid i insert the text in a textbox outside the datagrid.
the textbox wraps the text if it doesnt fit to the textbox length.then i push a button and insert that text in a database. then i want to display this text in a datagrid.i use two options in a label or in a textbox in a templatecolumn but with the textbox <asp:textbox ID="textbox1" runat="server" style="overflow:hidden" Font-Size="15px" BackColor="#FFFFC0" TextMode="multiline" Width="750px" Wrap="true" borderstyle="None" BorderWidth="0" Text='<%# Databinder.Eval(Container.Dataitem,"text_caption") %>'></asp:textbox>
i receive only the first two lines
and with the label
<asp:Label ID="Label112" runat="server" BorderStyle="None" Width="750px" BorderWidth="0" Text=' <%# Databinder.Eval(Container.Dataitem,"text_caption") .ToString.Replace(chr(13),"<br />") & "<br/>" & "<br/>" %>' ></asp:Label>
if the text is too big without an enter(that text wraps in the outside inserting textbox) then the datagrid width becomes too big although the text is diplayed normal with new lines so in the datagrid i have much space without characters the textbox that i use to insert new text is here <asp:TextBox D="tbox_text_caption" runat="server" Height="232px"
Style="left: 400px; position: absolute; top: 8px" MaxLength="750" TextMode="MultiLine" Width="752px"

I am dynamically bind the textbox in the data grid and in the text box change event i need to add the numbers in all the text box and show in the separate label.
I am using the text box change event and post back to true, I can able to calculate the result but the problem is that on text change itself i need to calculate and show the result, but in my case, when i move the focus from the that text box, the results calculated and focus get lost.

I was using the VisualTreeHelper trying to locate a textBlock inside the datagrid columnHeaders. I have just learnt that : "The Header object of the DataGridColumn is actually the visible header of that column, whatever you set it to be. DataGridColumn is not part of the Visual Tree so there is not direct way to access the DataGridColumnHeader for it (we can't even be sure it exists yet)... " This has set me back by a couple of days. I tried to convert the suggested code to vb.net in order to use it but I don't seem to get it right. The code in c# is :
Code:
ataGridColumnHeader headerObj = GetColumnHeaderFromColumn(column);
private DataGridColumnHeader GetColumnHeaderFromColumn(DataGridColumn column)
{
// dataGrid is the name of your DataGrid. In this case Name="dataGrid"
List<DataGridColumnHeader> columnHeaders = GetVisualChildCollection<DataGridColumnHeader>(dataGrid);
[Code] ...
How to apply it in my scenario shown below. I want to access in order to rename the textblock 'columnHeaderName'. How can I do this?
Code:
<Datagrid>
<Datagrid.Columns>
<DatagridTemplateColumn Header="header1" Width="100">
<DatagridTemplateColumn.HeaderTemplate>
[Code] ....

I have a Datagrid control which is populated with data from an Access database when the page loads - a simple 'Select *' command. This page also contains a text box and a button, the idea being that the user can then filter the data by entering a value in the text box and clicking on the button to pass the new parameter to the datasource.
However, I cannot get this to work, I know it has something to do with 'IsPostback', but I am at a loss. I have tried variations of the following in the code behind page but to no avail.
