Forms Data Controls :: Setting Headertext Of Gridview Dynamically
Jul 22, 2010
Is tehre anyway to set the HeaderText dynamically on a gridview? I'm trying the below, it kind of works, but the problem is on the initial load nothing shows up, but when I postback then the new text populates:
grdvMyTest.HeaderRow.Cells[5].Text = GetTheCalculatedDate();
I've tried that in both Page_Load and grdMyTest_Load, but same thing happens in both. When the page initial loads the column header text is blank, when I click something causing a postback it pops up. I don't have a IsPostBack check around that line, so it should be running regradless. I'm guessing I'm doing it at the wrong event, either too eariler or too late.
I am using Templates in GridView, but now I have to change the "HeaderText" of each column from code behind. I don't have <HeaderTemplate> so therefore I cannot use FndControl() in header row.
Is there a way to change the HeaderText of each colum without using <HeaderTemplate>
Here are the templates of the GridView which I am using
I have a GridView whose AutoGenerateColumns="False". However, I don't want to statically specify the HeaderText for the columns in HTML markup. Rather I'd like to set the HeaderText to be the name of the underlying SQLDataSource column name. How can I do this?
I am using VS2008.I am binding dynamic datatable to gridview. I have few dropdowns and textboxes in gridview. I have dropdownlist(ddlTrCodeNw_)in gridview foooter template. Based on the selection of Trcode value few controls will be enabled,disabled,visible,hide. in gridview.
<asp:GridView ID="gvAPPost" runat="server" Width="100%" ShowFooter="true" AllowPaging="true" AutoGenerateColumns="false" onrowcommand="gvAPPost_RowCommand" onrowdatabound="gvAPPost_RowDataBound" > <Columns> <asp:TemplateField HeaderText="Discount %" Visible="false"> <FooterTemplate> <asp:TextBox ID="txtDiscountPerNw" runat="server" Width="40px" Enabled="false" Visible="false" ></asp:TextBox > </FooterTemplate> <ItemTemplate> <asp:TextBox ID="txtDiscountPer" runat="server" Width="40px" Enabled="false" Visible="false"></asp:TextBox > </ItemTemplate> </asp:TemplateField> </Columns> </asp:GridView> Intially I set TemplateField HeaderText also Visible="false". so i have written the condition in ddlTrCodeNw_SelectedIndexChanged. Now when if(ddlTrCodeNw.SelectedValue=="24") { txtDepstNw.Enabled = true; txtDepstIncNw.Enabled = true; txtCrdtNw.Enabled = false; txtCrdtIncNw.Enabled = false; lblDiscTrcodeNw.Visible = true; // I want to show this TemplateField HeaderText also when i need. }
I can I show TemplateField HeaderText also whenever i need.
I have a grid that is built as well as populated dynamically through c# code. The grid has 3 columns(3 bound fields). And data is being populated in those bound fields through c# code programatically.
Elaborating my question: I have 3 bound field columns(col1, col2 & col3) . I have to increase the rowspan of col2 and col3 headertext's to 2 i.e I want the col2 and col3 header texts to span across two row cells. But the col1 header text should span across just 1 row. And the extra rowscell that is created under col1 due to the increase in the rowspans (of col2 and col3 boundfield headertexts) should be populated with some random text, i.e something like XXXXX
how to load Gridview HeaderText values from resource (.resx) files.I want to display headertext values for Gridview based on two different application dynamically.
I'm working on setting up a Gridview that dynamically creates new "columns" after a set amount of rows. To do this, I bind a datasource to the Gridview and then add new cells and shift the other items into those cells. I seem to be having an error with the link buttons that I move around. All of the items get put in there correct location, but for some reason, when I click a link button that has been added to a new cell, the sender's text is the LinkButton in the original cell's text. Does anyone know why this would be happening? Is the gridview not meant to be manipulated after it has been data bound? This is the code that I use to update the gridview.
In the datapager, is there any way to set the NextPageText and PreviousPageText properties dynamically so the NextPageText is set to the title of the the next story in the dataset?
I am adding linkbutton dynamically (actually above snippet tells what I am actually doing, in reality TableRow and TableCell are added dynamiccally). My problem is, I am not setting height of linkbuttuon which will added dynamically. I have no idea what text I have to add to linkbutton.
What I want, after all the link buttons are added, iterate through each added lin button, get the height of each linkbutton, store the max height, then re-iterate throgh the link buttons and set the height of each link button to max height.
however everytime i reload the page,backcolor disappears.If i move it out from IsPostBack block ,it works fine but i want to load grid only when the page loads for first time(inside !Page.IsPostBack).
I cannot figure out why HeaderText or validation controls always fallback to default culture - even though rest of the controls are in correct culture.
I have a GridView with HeaderText specified in this way>
I have a Gridview, lets call it GVDistinctDate which displays Distinct Date in one column only. For example: I got 5 rows, and 1 column where the column only display distinct dates such as 02/04/2010 | 03/04/2010 | 04/04/2010 | 05/04/2010 | 06/04/2010 where obviously this dates come from a table in the database.
Now i want to take those dates in GVDistinctDate and assign it to another gridview, lets call it GVReport, as column Header Text. For this GVReport, the first column would be StudentID where a list of studentid will be displayed, and then starting from the second column onwards, where the Header Text would be the dates from GVDistinctDate, will display a Status of absent or present according to the studentID and the corresponding date. How do it get the dates from GVDistinctDate into the column Header Text of GVReport?
AND how do it display the Present or Absent status based on the studentID in column 1 GVReport and the dates on the Header Text? Below are the codes of how i got the distinct date into GVDistinctDate
[Code]....
The code below is for GVReport and the comments are where i tried to put in the dates into the column header text.
[Code]....
There is a problem here: GVReport.Columns(k).HeaderText = headerText Error:Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index
I have a gridview with a bound column,a template field with an editable textbox and a template field with a readonly textbox.
The bound field value is coming from database. I will enter a value to the editable textbox field. I want to set a value to the third cell based on the entered value in second cell . If the second cell is lost focus i want to set the value to third cell . If the solution is with a javascript function i will be very happy.
