C# - How To Set A Gridview Column Width When Binding To A Datatable
Apr 29, 2010
I am binding a table to a gridview in asp.net as such
grdIssues.DataSource = mdtIssues;
grdIssues.DataBind();
The problem is I cannot then control the column width, asp.net seems to decided on it's own what width each column should be. Methods such as
grdIssues.Columns[0].ItemStyle.Width = 100;
grdIssues.Columns[1].ItemStyle.Width = 100;
don't work because the columns are created dynamically. I cannot believe there isn't a way to do this short of manually creating each column and filling each row.

I have a GridView, in which the width of each column is dynamic and changes depending on the dataset. I need to get the width of each column for use in my PDF exporter, but the column/cells width is always '0', presumably because I haven't set the width property.
Is there a way around this?

I'm using VS 2010. I have a GridView with few template columns. I want the 2nd column to not be visible at all, but still to be existed so javascript will be able to see it's value. Does someone knows how to set this width value?

I've coded a GridView in the markup in a page. I have coded a DataTable in the code-behind that takes data from a collection of custom objects. I then bind that DataTable to the GridView. (Specific problem mentioned a couple code-snippets below.)
GridView Markup:
<asp:GridView ID="gvCart" runat="server" CssClass="pList" AutoGenerateColumns="false" DataKeyNames="ProductID">
<Columns>
[code]....
Goal: I'm basically trying to find a way to update the data in my GridView (and more importantly my cart Session object) without having to do everything else I've seen online such as utilizing OnRowUpdate, etc. Could someone please tell me why gvCart.Rows is empty and/or how I could accomplish my goal without utilizing OnRowUpdate, etc.? When I execute this code, the GridView gets populated but for some reason I can't access any of its rows in the code-behind.

I have been looking for an answer to this for awhile and haven't found what I am looking for. I have a GridView with 5 columns. One of those columns is a very long string with instead of " ". I need to be able to fix the width of the column and have word wrap take care of the string till the end of it. I have tried all the properties on the gridview to get what I need but the span always stretches out horizontally and never wraps. Here is my gridView code
<asp:GridView ID="resultsGrid" AutoGenerateColumns="False" runat="server" AllowPaging="True"
AllowSorting="True" PageSize="20" OnPageIndexChanging="gridView_PageIndexChanging"
OnSorting="gridView_Sorting" PagerSettings-Position="TopAndBottom" PagerStyle-HorizontalAlign="Center">
<PagerSettings Position="TopAndBottom" />
<Columns>
<asp:TemplateField>
<ItemTemplate>
<%# Container.DataItemIndex + 1 + "." %>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField Visible="false" SortExpression="record_id">
<ItemTemplate>
<asp:Label ID="lblRecordID" runat="server" Text='<%# Bind("RecordID") %>' Visible="false"></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Note Type" SortExpression="business_content_type_cd">
<ItemTemplate>
<asp:Label ID="lblNoteType" runat="server" Text='<%# Bind("NoteType") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Author" SortExpression="author_user_name">
<ItemTemplate>
<asp:Label ID="lblAuthor" runat="server" Text='<%# Bind("Author") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Date" SortExpression="content_dttm">
<ItemTemplate>
<asp:Label ID="lblDate" runat="server" Text='<%# Bind("Date") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField>
<ItemTemplate>
<asp:Label Width="100px" ID="lblData" runat="server" Text='<%# Bind("NoteContent") %>'></asp:Label>
<asp:HyperLink ID="linkMore" runat="server" />
</ItemTemplate>
<FooterStyle Wrap="true" Width="100px" />
<HeaderStyle Wrap="true" Width="100px" />
<ItemStyle Wrap="true" Width="100px" />
</asp:TemplateField>
<asp:TemplateField SortExpression="size" Visible="false">
<ItemTemplate>
<asp:Label ID="lblSize" runat="server" Text='<%# Bind("Size") %>' Visible="false"></asp:Label>
</ItemTemplate>
</asp:TemplateField>
</Columns>
<PagerStyle HorizontalAlign="Center" />
</asp:GridView>
I am not a fan of what I have to do but the client wants what the client wants(I need to mimic the user interface of a mainframe screen).

I have a gridview that I need to get the width of columns for after the gridview is databound. I have to have AutoGenerateColumns=true because the columns for the datatable that the gridview is bound to is not going to be fixed. The problem I'm having is the gridview columns collection is not populated when AutoGenerateColumns is true. Is there anyway I can get the width of each column after the gridview is databound? I've tried using RowDataBound and going through the tablecells but the width is 0 for every column.

I want to set header column width for grid view. I tried HeaderStyle-Width="30px". But it is depending on Item columns. The column width is setting based on item value. But I want fixed width even if it has value or empty.

How is it possible to change the displayed order of columns from a DataTable?
For example, dataTable "dt" contains two columns "a" and "b". I bind it to a GridView like this:
gridView.DataSource = dt;
gridView.DataBind();
But I'd like the GridView to display "b" first (leftmost).
Important point: I'm using this to export to Excel and there's no actual output to screen, using:
HtmlTextWriter htw = new HtmlTextWriter(sw);
gridView.RenderControl(htw);

I have a gridview with empty data template. In this empty data template i have a table(HTML) with 4 columns. When user enters data i want to save this in a datatable temporarily at a button click event.. Again if user wants to add one more rows data that also should be added to the same table where i added previous row data. So now the datatable has 2 rows. Like this he may add any no of rows. What i want is all the rows should be displayed when i bind datatable to gridview..At the click event i am adding 1 row at a time to the datatable

i need to set the column width of my gridview.
However the the column in the gridview is dynamic created which might more or less depend on system logic.
I have try to set the column width in row_created event, rowDataBound event, but it show me that no column is available by using gridview.columns.count.

I have been searching the internet for a solution to this for hours. I have tried all of the following methods to set the column width on my GridView control:
1. <asp:TemplateField HeaderText="ColumnHeader" ItemStyle-Width="100px">
2. <ItemStyle Width="100px" Wrap="False" />
3. GridView.Columns[0].ItemStyle.Width = 100 both on the PageLoad event and, out of desperation, on the RowDataBound event.
I have tried these settings by themselves and in combination. I have also experimented with different CSS width settings for the GridView and its containing <div> (including none) to no avail. The GridView columns are always equally spaced and wrap the row description text in the first column in a rather ugly fashion. As this needs to be fixed for a presentation to a client on Monday, I would be eternally grateful to anyone who could point me in the right direction.

I am trying to set the width of each column within my gridview. Problem is that none of it is working. I have tried setting the whole grid view to 100% and then break down each individual column to a certain percentage, tried manually adjusting Header Width, Item Style width, tried setting it in code, I have tried just about everything and the column doesn't want to budge. The only time I can adjust the width of the column/cell is when I do it in SQL, but because they are requesting the tooltip to preview the comment I would like to pursue my options doing it on the page itself.
//Code protected void grdComments_RowDataBound(object sender, GridViewRowEventArgs e)
{//Setting the tooltip for the comment column and column width.
grdComments.Columns[3].ItemStyle.Width = Unit.Pixel(100);
//e.Row.Cells[3].Width = Unit.Pixel(100);
e.Row.Cells[3].Wrap = false;
e.Row.Cells[3].Style["overflow"] = "hidden";
e.Row.Cells[3].Style["text-overflow"] = "ellipsis";
e.Row.Cells[3].ToolTip = e.Row.Cells[3].Text; }

I have a gridview and I want to fix the column size to a certain size regardless of the length of the data in a given cell.
I have tried everythign I can think of from
gvwProjects.Columns[1].ItemStyle.Width
gvwProjects.Columns[1].ItemStyle.Wrap
to setting the length of the lblContol in the template but no matter what I do the column size automatically increases beyond my fixed size to meet the size of the longest cell in the bound datatable.
