I am trying to access column value by using DataBinder.Eval on RowCommand event of Gridview. It always return NOT SET TO ANY INSTANCE error for eveytime. I know how to do this by employing a label control in ItemTemplate, but am trying to find a way to bypass.
Error returned by DataBinder.Eval(row.DataItem, "LinkToInvoice").ToString
the problem arise when this datacolumn in my database have a null value, it throws an error ....how can I get this to work so that DataBinder.Eval can take a null value?
I would like to read from a data reader (or other) and write to a grid of some kind one row at a time in a loop. I prefer this rather than load a data bound grid control all at once. I need to do this because I have to perform some calculations on the data before writing each row.
I've got an asp.net application (written in vb.net). I have a results page that spits out some calculations. Ineed to write out that output to MS Word. The catch is, this happens within a folder that is secured (only users that are logged in can generate the word document).
Here's what I'm using to gen the document. This works ok when running it locally, but not when loaded to GoDaddy hosting.

My code seems works fine locally. However, after loading it to GoDaddy it only works on a non-secured (not subject to ASP Membership), but when trying to use it in a secured folder the page clocks and eventually closes out.
i just cannot work this out... i have a gridview and when a user clicks on a row the checkbox unchecks itself... when the user clicks the row a sqldatasource.update is called from the selectedindexchanged event, problem is when it writes back to the database it writes back every checkbox as unchecked, i want just the row that's selected...
what i can't work out is i've tried putting a where clause in the sqlcommand which is something like where primarykeyID = gridview1.selectedvalue... now it won't write anything back to the database...!!! ... once i take out the where clause, it writes back to every row..!!
I'm writing an asp.net site in vs2005 asp.net c#, I'm using google charts api and found a lot of disadvantages. Which tools do you use and recommend? I need charts, pies, bars and data presentation, even payed systems can be considered(<200$ per server). I used in the past the buid in reports viewer which has a lot of bugs.
To create a DIV in my body but how do I then add innerHTML to this control? Or can I directly add an Label to the newly created control and set tag ones text?
search for a item, display the results in a datagrid, have a LinkButton (per item in the datagrid) to show a popup modal and insert this data to a new table. I have the search, the datagrid, and popup modal all working. I need help with the add button in the popup modal (which insert into a new table in the db). In my datagrid im using DataFields - how would I get access to this in the codebehind so I dont have to re-query the db again for the ID that i'm trying to insert?
I have gridview and sqlDataSource. In edit mode, if the user checks closed checkbox closeDate parameter is set to today and appears in a label near to checkbox. So, I need to control isClosed checkbox and then if it is true closeDate=GETDATE()
[Code]....
Only CloseDate parameter need to be set in codebehind, other parameters handled in gridview.
I have multiple questions about doing gridview in code behind.I used this code to fill my gridview at runtime.
[Code]....
My questions are:1. How to edit the column headers? When I bind the database to my gridview, obviously, the column headers of the database will be binded. For example "First_Name", I want to edit the column so I can omit the underscore.2. How to edit the column width?
I have a DDL bound to a sqldatasource where the dataTextName is the storeName (varchar) and the dataValueField is the storeID (PK Int). I'm holding the value of the storeID in a user's profile (using ASP.NET membership profile). So, when a user is created, they're assigned to a store (or not...it's optional). When I edit the user, I populate the DDL with all the stores in the table, but I need to set the selected item to the storeID in the profile (if it exists)...I'm not sure at what point to do it though. In my codebehind, I bind the ddl to the datasource and insert an additional item: if not page.ispostback then REM: bind the company ddl
This is my gridview with an item template, I have NO boundColumns.TO get data to codebehind I use Eval(" <Field name >"), but this returns something to a control. Not making data available for codebehind code for general use.
Question: As I have no boundcolumns I dont know how to get data to codebehind to to use as I wish??
