i have an export to excel functionality on my page and when i export my this data to excel the backcolor of datarows after export is white.
The backcolor of rows after export to excel should be same as that of aspx page.
How can i get it done?
Here is my logic i tried in rowdatabound event-
[Code]....
if a cell background colour is dark (not just black, could be many shades of grey) and then change the cell font to a lighter colour so as to contrast the background colour and make the text easier to read?
View 4 RepliesI've created a GridView as follows:

In my SQL DataSource, I also have a field called 'ClassLevel_Colour' which stores a colour value (for example: #9251ed)
What I'd like to do is colour the cell 'ClassLevel_Value' with the colour set in ClassLevel_Colour.
C# code I need to write - presumable for 'GridView_Classes_RowDataBound'?
I have a gridview which is bounded with a Datatable. I have a button column in the gridview and on its click I am updating other row data and color. Data is been retained and color of the cell.
But when I am clicking other rows button, that particular rows color is retained but remaining color is again reverted to default. How can I rectify this.
when I used a code of exporting gridview into excel this code worked for a new website which is without masterpage.
my code:
public override void VerifyRenderingInServerForm(Control control) { }
protected void BtnGenerateReport_Click(object sender, EventArgs e)
{
Response.Clear();
Response.Buffer = true;
Response.AddHeader("content-disposition",
"attachment;filename=GridViewExport.xls");
Response.Charset = "";
Response.ContentType = "application/vnd.ms-excel";
StringWriter sw = new StringWriter();.....
Now the same code when I copy it in my project having masterpage . there is no compiler error but it is genereating excel file withno data in it but in fact there is data in the grid view at runtime.
I'm exporting a Gridview to excel. I get all the gridview header and content in excel in addition to that i need to add a header text like report name in header of the excel sheet with line break in header.
I tried the solution in this link [URL] by adding
Table.Caption = "Header Text"
Table.CaptionAlign = TableCaptionAlign.Top
but i get error Reference to a non shared member requires an object reference.
I have a project in vb with a gridview in a multiview and i want to save in a workbook excel the gridview displayed data.

I have the following scenario shown below
Label: Name
ID Qty

Kindly note, the ID. QTy are currently in a gridview and the Label is a label on top of the gridview. I would like to export both the label and the gridview to excel...how can I do this.
This is an ASP.NET 3.5 project being created with VS2008. One page contains a gridview with six columns. One of the columns displays standard, 17 character , Vehicle Identification Numbers (VIN). The VIN numbers display normally when the page is rendered. However, when the gridview is exported to Excel, the VIN numbers change. For example, in the gridview, the VIN might be 12345678912345678But when the gridview exports into Excel, that same VIN becomes 1.23457E+16The value of that Excel cell changes to 12345678912345600, changing the last two digits from 78 to 00. It does this for every VIN in the gridview table.I did some Googling but couldn't find anything specifically on this issue. Has anyone seen it before? Is there a way to format the column in the gridview so that Excel will accept it as literal text? I tried programmatically adding a style called 'text' to that column but that had no effect on the outcome. All of the other columns are behaving normally.
View 3 RepliesI come across the technique on how to apply a different CSS class to make a row stand out from the others. However, the original code is for gridview whilst I am trying to get it works on a listview. The original code for the gridview is as follows and how to get it done on listview.
