Forms Data Controls :: How To Convert A Varchar Column To Int And Sort In Grid View
Jul 21, 2010
I have a grid view with manual sorting. In some cells, the data are numeric and datetime. But due to some constrains, the data type on tables are varchar. The problem here is when I sorting those numeric data, it is treated as varchar.Eg: 1, 12, 13, 2, 23, 3, ...But I wanted the order to be: 1, 2, 3, 12, 13, 23, ...I have tried these method, but it doesnt works.
i have a grid view with some coulmns like Name,Phone no etc with Edit,Delete column in grid view. I click a row in grid view to Edit,it goes another page where i can edit all fields .Once i update i redirect the page to gridview. I want the grid view to remain in that particular page say 4 of the grid view
I have a GridView in ASP.Net 3.5. I added BoundFields as columns, set DataField and Header Text. Total I have 6 columns like that. Although I set "AllowSorting=True" in design view, when I run this page, all the columns didn't have hyper link that I can click on it and sort that particular column. I bind this column at code behind by using datatable. gv.DataSource = dtDispatch gv.DataBind()
I am sorting the grid using DataView's "Sort" property. I am passing sort expression and the order in which the grid is to be sorted(ASC or DESC). But the problem is, since the column on which I am sorting the grid is listing the intergers, the sorting is happening as if it is a string. But I need integer sorting rather string sorting on that column.
The grid displays below as ascending order(string sorting) 55 77 8
But I need the columns to be displayed like this(Integer sorting) 8 55 77
I have this code that once a column in gridview is clicked, it sort the record. Can someon explain to me what does
static Int32 cntsortSecurityID = 0; // declare var to hold 0 or 1 // what is this, I dont understand why. what is the meaning of zero or One in this case . Oh yeas, the code is working for me, but I need to understand the concept behind it.
wondering if someone can possibly help me out with a gridview. I have data coming into a grid and I know how to filter the data using one dropdown, I'm trying to get a little more advanced now. I'd like to filter using three dropdowns.
This is what I have so far: I don't know how to hook the downlists to the query?
If the grid column is clicked to sort i dont want to retireve data agian, i can get it from viewstate, but i dont know if that triggered the post back or if the ImageButton on the page triggered it
I got this code which bind a datatable to a grid view. After the binding, i wanted to add additional column to the right of the grid, how can I do that? My codes below failed to do it.
[Code]....
The Header value of "ID1" is shown, but the cells only shows a '-' instead of 'New Column' sign.
How can i create a hyperlink to Grid view column, when i click this column it should open Word documentnt.Each Column row values does have seperate information.
Now I wanted to hide, that is to make some of the columns visible false.
First how can I do that, Second should I write the code in the same page_load event or I should write the code some where else, cause when I add this line of code
I am in the process doing drag n drop for gridview by column cell. For example: there is 5 cell in a column, user are able to drag the first cell and drop it as 3rd cell.I have find through the internet but has find no resource on it.
I have a GridView control in my aspx page with a column that represents logging levels. Instead of displaying the word, e.g"Info", "Debug", "Error", etc. I want to display an image from a file. It seems like I may be able to do this with a template but I have been unable to find any examples of exactly how I would do this.
If "Info" then display "images/info.gif If "Error" then display "images/error.gif etc.

I have a grid view that needs to be shown group wise. The grouping of the data should be dynamic and that is based on the column that is selected.
In general it should list all the rows and based on the coloumn header selected, all the rows should group by that column and should be listed under it. That also needs the template column for the check box and while group by there should be a check all option available for each group.
Even having the collapse and expand option for each groups is required.
I currently use VS 2005 and later will use 2008 and 2010, but will use the aspx code and not xaml.
