Forms Data Controls :: How To Set Selected Value Of Dropdown In Gridview After Gridview Databound
Nov 30, 2010
I have a gridview with dropdown boxes. As soon as the complete gridview is databound, I want to loop through ALL the rows and set the values of the dropdown boxe in a row based on the value of another column in the same row. The gridview is databound, all data shows up. The condition "If ddl.Items(j).Value = searchstring Then" evaluates as true, but somehow the selected item in the dropdownbox is NOT changed and remains "<ignore>"
I put a sql statement into the textbox,then the result will be bound to the gridview in the page. first time,sql statement is "selecte * from A(B)",and the gridview is ok. second time,sql statement is "selecte * from B(A)",then the gridview will throw a exception the exception is "A field or property with the name 'aa' was not found on the selected data source. i have two tables A and B."
I am developing page for maintaing employee record using Visual Studio 2008, MS SQL server 2005. I am able to fetch and display all the employee information in gridview, the gridview have the dropdown list to display the employee type [ Part Time, Full Time, Permanent , Contract ], in the item template i am having dropdown list. IN the dropdown list i am displaying this. But While saving the record in gridview the droppdown selected index are changed to 0 of other dropdown list.
the user may be change the dropdown value from permanent to contract, or so. but while click on the save button in gridview, all the previous selection are gone, and always showing the first record of dropdown list. I know this is happening because we are doing dropdown list bind on onRowDataBound.
I have a gridview that had a field called "GenericNameHepDrug" within the row. It's not the key field. I have an insert button that opens a formview in insertmode. How can I get the selected value of generichepdrug into the formview that opens when the button is clicked? I am using VB.NET 2.0.
here is some code from the source:
Here is what I tried to do in the code nehind of the button3_click:
CLearly I am lost. I have been working with ASP.NET VB for 2 months. I'm in over my head with figuring this one out - I've been at it for days.
i have to a grid view and the datasource for it is a table coming from the database the table containing sequence numbers for example if the sequence number is 1 then i want to add a row just above this saying it is the start , the entire row should give some information .
i tried to find related thing but no luck, waiting for some replies to move further
I need to be able to get the value in the "first" row of a Gridview as its getting or right after it is displayed.
I thought this would work but its coming up null.
I'm using the DataBound event to get the value of the control of a selected row...assuming the selected row is the first row which is probably the error of my ways. Any ideas how to get at this value easily?
i have a dropdown with month names if the user has data for the month tht is selected then gridview displays the rows with day nos as per the month but if the gridview has no data for the same the dropdown or gridview via some event should call a insert procedure to insert data into the table for tht month with daynos ad rebind the gridview witht the rows just created
I have 2 gridviews, the first gridview is row-selectable. When selected it displays some details in a second gridview. What I need to do is position the second gridview next to the first gridview's selected row.
I have two gridviews, where the first is databound to a sql table (but does not display the primary key info), and want to filter the data displayed on the second gridview by using the primary key info from the first gridview table, indicated by the selected row in the first gridview - how I could achieve this? its kind of like using the gridviews as a menu and sub menu display!
The original Item Template was Enabled ="false" I changed this so that you did not have to set the row to a state of edit in order to just select a row. I enabled it so that you could "select" any row with out putting it in a state of edit. the only value changing is if its selected or not. What i am trying to do is use the Data Source Update method to update the bit in the database based on the check box. Currently Update() returns 0. I believe this is because the row/feild is not marked as changed so the Data Source does not see it as something that needs to be updated.
What I am hoping for out of this is post is a way that the rows whom check value has changed to be marked as changed/edited so that the data source will update the database with the values of the check boxes. If all rows are updated this is acceptable as well. I know this is a super simple solution but i have been out of the .NET for a little bit.
I have a stored procedure (For Eg: sp_GetAvlData) that accepts a number of parameters, 3 of which are TimeFrom, TimeTo (as varchar) and TimeInterval (as int), formulates a Dynamic query and executes itself. So for instance, if I call the proc as follows:
dtAvl is the datatable containing the results of my stored procedure.
The next step for me is to make each of the cells (except the cells in the first column) as a Hyperlink so that when clicked upon a cell, it populates 2 textboxes with the selected Timeslot and Name or ID (ID field is not displayed in Gridview). The textboxes are located on the same page but outside of the Gridview control.
The Challenge that I'm facing out here are:
1) As you can see, the field names being generated are not fixed and I have no control over them.
2) Because the field names are not fixed I'm not sure I can implement this using the Templatefields or BoundFields of Gridview.
Is there any way to achieve the Hyperlinking of these cells within the Gridview?
