Forms Data Controls :: Show Column Headers When Gridview Returns Empty Data Set?
Oct 15, 2010
I have in my code a gridview that I redirect to excel, it works fine when I have data in the data set. waht I want is to show column headers when there is no data right now what i get is empty sheet.
I just hit the same problem as described here: [URL] - GridView paging with ObjectDataSource. I see the column headers but no data, and I know for a fact my method returns a DataTable with data in it.
I've been trying for the past few hours to add mutliple headers to my grid view but keep failing to get it to show. There's plenty of examples online that I found but can't seem to get the most simplest to work. Below is the code I've been using with no success. I even tried changing the "TableCell" o "TableHeaderCell" but still yields no headers as expected. Anyone know what I could be doing wrong?
i have a gridview which is populated from a stores proc using pivot tables. The column are created dynamically apart from a total column which is created as a template field. the gridview looks like below:
CPW EE Foh H3G IND O2 ORG P4U T-M TSC VIR VOD Total
Stores Visited
70 0 0 12 0 16 18 7 11 1 2 8 145
i need to add a hyperlink to each gridview cell and when that cell is clicked pass the header text through the querystring to another page. I can access the cells value ok and pass that through but i cannot seem to access the cells column header text. when i response.write out a count of the gridview.columns it brings back 2 which is the template fields but not the dynamic fields i have tried this on the rowdatbound, rowcreated, page_load and page_unload. the count should be 12 its like it cannot find the dynamic columns at all. ?
here is my code for populating the gridview
[Code]....
and here is my gridview:
[Code]....
i am also moving the total column in this code
[Code]....
and calculating my total in this code and adding my link to the total colum (which works fine)
[Code]....
now i just need to somehow add a link to the other cells and somehow get the value of the header text for that cell clicked.
I have boundfiled column inside gridview and made the column as invisible by setting visible="false".
But while exporting the gridview to excel I am getting the Header text alone exported. Wherever the column's visibility is set to false the header text should not be exported. After binding the gridview I have set the column's visiblity to false so it won't export the column values.
The problem is to stop exporting the header text to excel. Let's say column index is 10
I recently applied a javascript code from article "Dynamically freeze ASP.net Gridview header using Javascript" found here, ASP Snippets Article, to my page. The javascript works great, but somehow, it's overriding my CSS code for the headers. When I refresh the page, I can see the headers with my CSS in place for just a fraction of a second before it is replaced with generic styling. I am not a javascript person, so really can't troubleshoot the problem. I have a style sheet with the following code.
Scrollable GridView with Fixed Headers inside ASP.Net UpdatePanel using jQuery Plugin. I have one more question in that. How to adjust the width of the columns headers because for some of my gridviews the headers not showing the proper format. in the gridview I gave HorizontalAlign="Left" and in the columns I gave
I have a gridview and i wanted to add a row when the gridview is empty, so that the header would be shown anyway. I have read about it on the web but i can't quite understand where exactly should i add the row.
My grid is binded by a sqldatasource. I am already adding a second header for the grid (to display some filters, and they need to be shown even if there are no results so that the user can perform another "search"), on rowCreated event, so, where am i supposed to add the row? Which events are fired even if the gridview is empty?
I've got a gridview in which I have a footer that I use to insert rows into the grid. However, if the grid is empty no data is displayed (including the footer). Is there a way to still show the footer row so a user can insert additional rows into the grid despite it starting out as empty?
I have a gridview with insert new row controls in the footer binded to sql datasource. I want to show the footer when the datasource is empty. Although the empty data template is there but any other solution you fellows can tell me ?
I am trying to show the footer template of a gridview on page load when there is no data in the database. The reason why im saying page load is that I have code to actually pull data from the database instead of a datasource.
I m Using DataList Controll for the time being. But i wana use DridView Controll that should display Data Horizontally. Is it Possible? if Yes then How?
I have the following gridView and I would like to add a 'free format textBox' to 3 of the column headers, to allow filtering. Much like here If I could/somehow achieve this that would be amazing. I can't use dropDown lists like many of the examples I have found as these lists would be too populated and proving too unfriendly to use.
I'm using a GridView to display some ifnromation in ASP.NET. I need it to simply display 0 in the gridview fields (there's only ever one row returned) if the dataset is empty, plus of course display the headers.
Now in server side i am trying to hide this column but failed !!
protected void gv_RowCreated(object sender, GridViewRowEventArgs e) { if (e.Row.RowType == DataControlRowType.Header || e.Row.RowType == DataControlRowType.DataRow) gv.Columns[2].HeaderStyle.CssClass = "hiddenClass"; // here i am setting display:None using css class }
I have a gridview, which contains a template field with a button. On this button, I want to show and hide another column with this one button. I don't want to use Java Script because my site already uses a lot of this and AJAX. So, can someone show an example of some code behind, which is what I want to do on how to show and hide another column on a gridview?
I have never work with a repeater and after a lot of research I got to the conclusion that this is the control I need to use for what I have to do. I need display data but I will need 2 headers and after some sort of amount of records the headers will repeat again. In this page you will find an example of what I'm trying to do http://ratings.fide.com/view_source.phtml?code=45276 I don't know if a repeater is the right control but i thin it is.
