how to access each row of a grid view using FOR EACH loop............
View 2 RepliesI have search for a long long time and could not find a solution to access to grid view's column properties. I have binded a grid view through this method, the bindGridView function will return a table with columns and rows.
The problem here is I cound not access to columns properties such as Grid_View.Columns.Count or Grid_View.Columns[0]."something". It seems like the grid_view does not have any column. But I can access to the Rows properties.
I have put this code within a (!IsPostBack) and set the AutoGenerateColumns to true?
I need to access to columns badly as I need t add additional column to the binded grid view.

I am doing a online web application whereby user is able to enter in new template as well as search for template. The Add template is located outside the grid view and if user clicks on the button, it will load the grid view that is populated with data as there is a row of empty fields at the bottom. However when I click on the Add Template button, the grid view does not appear.
This is my business logic that I used it to search for records as well to click on the Add Template button to add in new records:

i have a grid view which displays only one value and i need to extract that value and display it in a textbox?
View 4 RepliesI am working on ASP.NET 4.0 application.I want to bind the data in a datatable to a grid control and i want to do some formatting. I want to merge the cells or hide the cell border in the first three columns (Merge every 5 cells in a column). And Vertical align the text to center. Also i need row border at the end of every 5 rows.
For example, If i am binding 10 rows to the Grid i need row border only at the end of 5th and 10th row. And merge every five cells only in the first three columns. All the other columns should not be changed. I also want to change the background color of the cells in all rows based on the value in that cell. How to achieve this in ASP.NET 4.0 and which control can be used to display in this format?
If i have a page which displays all the data but with only a few fields, then i select one of the data and then i want to be able to view that data with all the fields related to that data on another web page.
I have been able to view the data in Grid view and enable the Select, Update, Insert and Delete. But not able to use the select button to view the information on another web page.
Have a GridView with a templated select button hidden and using
e.Row.Attributes.Add("onclick",Page.ClientScript.GetPostBackEventReference(this.grdMaster, "Select$" + e.Row.RowIndex.ToString())); to select a row .
When user like to update the datasource he will select one row from gridview then in selected indexchanged event i would display the selected row values beneath the form under the grid , Then user will update the contents displayed from grid and click an update button which is outside the grid . After updating the displayed row , i got to get the values of the next row in the grid and display them for next updation , i'e if users maually selects row 3 from grid then he can update the values using the update button and then on update click itself i'll have to display next row contents of row 4 and this process could go on .
I have a grid view that does add, edit update and delete. ( I draged the grid to the aspx page ) it is working. I would like to have the following : once I lick on edit, I open a form inside the grid view to edit the fields. How can I do that.
