Forms Data Controls :: How To Bind Grid View Columns Dynamically
Feb 9, 2010I am developing an application using ASP.NET with C#.NET.in my application i have a gridview control and radobutton list having the values as Manufacturer and Distributor. based on the radiobutton selected value,the gridview will bindedup.
i am using SQL SERVER 2005 as backend server. in my database i have one table with columns as
1.mfropendate
2.mfrclosedate
3.mfrawarddate
4.distopendate
5.distclosedate
6.distawarddate
My gridview has 3 columns as Opendate,closedate,awarddate.
if user select the radiobutton as manufacturer,only mfropendate,mfrclosedate,mfrawarddate have to bind. and if user select the distributor the remaining 3 fields will have to bind. for that i had write a storedproc as create procedure sp_GetDraftBids as begin select mfropendate as opendate,mfrclosedate as closedate,mfrawarddate as awarddate, distopendate as opendate,distclosedate closedate,distawarddate awarddate from draftbids end GO
i.e i had taken the alias names for that fields so that i will bind the only 3 columns to grid view as opendate,closedate,awarddate.
My gridview code is
[Code]....
here i had taken the same alias names as i have to bind only 3 columns to gridview.when i run my application i am getting the records in data table with column names as opendate,closedate,awarddate,opendate1,closedate1,awarddate1.i.e it does not allow the same alias name.
for two radio button conditions i.e for manufacturer and distributor the gridview binded with opendate,closedate and awarddate columns as i had binded the gridview boundfields withat names.
but when user select the distributor radiobutton i have to bind the opendate1,closedate1 and awarddate1 to the gridview. for that should i can i change the storedproc are any other solution is there?
Forms Data Controls :: Show Grid View Dynamically At Runtime?
Jan 11, 2011I have a gridview, in an update panel, that's populated by an object data source when the page loads. This same Grid View is going to use a different data source and slightly different columns collection at runtime. The columns collection will be very similar, with one column added and three removed. Is this the best way to do this?
The other solution would be to create another grid view and data source to use when needed. The two Grid Views can be toggled off and on to use the correct one as needed. I've done this and it worked well, as far as I can tell. I'm curious if there are performance implications because of the additional Grid views and data sources. Or, if there are other reasons not to do this.
Which of these two ways is the best way to do this? Should I toggle between the two Grid Views at runtime or modify the grid view(datasource and columns) at runtime in the code behind?

View 2 RepliesForms Data Controls :: Hide Column In A Dynamically Created Grid View?
Jul 23, 2010I have a dynamically created grid view in the load even of my web page. I am setting its data source at run time like
gv.datasource = someObject.getItems();
gv.dataBind();
Now I wanted to hide, that is to make some of the columns visible false.

Forms Data Controls :: Click Button Outside Grid View And Display The Grid View Upon Load?
Feb 9, 2011I 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:
