How can I export data from a Gridview to excel and once exported the data should be formatted in right to left (arabic) manner. How can I achieve this?
We have the requirement to export the data from the grid excel. We can't install the Excel on the server. The excel generated need to be in the printable format. The excel generated needs to have custom headers, footers, repeatble rows, columns and landscape / portrait orientation style.

i have 2 dropdownlist and gridview. Im trying to make a link after displaying the relational data in the gridview like below But how can i get the value and combine with the link
I have a datagrid which pulls data from a single database table to display it. However, this database table also contains information on the thumbnail URL for each record, and I would like to display the thumbnails for each record in the 1st column of the datagrid.
At present I have added the following to my datagrid:
[Code]....
So I presume the main challenge now is to set the Thumbnail.ImageUrl property to the correct file path in the VB.NET code. But how do I do this for each record? I am using a function to retrieve data for the gridview, which is based on the following:
I have a Table (in SQL Server) that is being updated roughly every minute or so with new records being inserted from various sources. The number of records inserted in this duration varies from a few records up to dozens of new records. I am using an update panel to rebind my data every minute to keep the GridView current. Now that I have the data refreshing I am looking for a better solution than reloading the data every minute. how to best keep my GridView up to date? Here is what I would like to accomplish:
1. Load the GridView and refresh the contents every minute. (60 second intervals)
2. When the GridView is refreshed every minute I would like to append only the new records to the existing grid, rather than bringing back the entire result set with each round trip to the database.
3. I would like a visual cue to identify the rows that have been inserted into the GridView. If new rows were to flash/flicker with a background color (yellow) that would be ideal.
Am I even using the correct control for displaying real time data, or are their other options? I essentially am looking to find the preferred method of displaying data that is being updated in real time in a web application. I'm hoping there is a solution involving AJAX but I haven't been able to find much on The Google. I am open to changing anything and everything about my approach -- this is largely a learning exercise. For testing purposes I am currently using LinqDataSource in conjunction with a GridView in an UpdatePanel being refreshed by a Timer control every 60 seconds. Informational: I have also started playing with the [URL] in place of the Timer control. However, for the purposes of this example I would be content to achieve the desired behavior using native controls as I have described them above.
I am doing a search function where when user enters specific value (either by keying product name or product code) into textbox, data will be displayed using gridview.
However i have problems displaying it in gridview.
here I can find some info on how to display data from my MSSQL database in something like old style tables (table,<tr>,<td>) becouse I used to done it like this in classic asp but i had a formula for calculating where to put tr or td and it becomed very confused, not to mention displaying gruped records like 10 on each page...I tried gridview in VisualStudio but I can not find any info how to use sql in it so I think it can not help me becouse it is to much predefined and I do not know where I can change code for it like what data source to use, sql and other important thing
I am currently trying to figure out the best way to handle a data formatting issue. I have a stored procedure that pulls back basically all the data I need, but using a gridview doesn't really give me what I need.
For example...currently the gridview displays data like:
I have a problem displaying data in a Grid View control when set a row to visible = false when a certain condition is true.
For example, if a DataRowData value has a condition set to true (custom in table) I set the visible property to false, so the data row will not be visible at run time.
The problem is that I'm using paging (10 rows per page) and if 8 of those rows fall into the true condition that won't show the row, that grid view page will only show two rows of data in page 1. The worst scenario is that if I go to page 2 of the grid view and all the rows (10) fall into the true condition, that grid view page will not show any data at all.
How can I show 10 rows of data at all times in a gridview? In other words, I would like to just show the visible rows at all times.
