Forms Data Controls :: GridView / DetailsView - Adding 1st Record To Table?
Mar 1, 2011I have a GridView and DetailsView on the same page.

View 2 RepliesForms Data Controls :: Dynamic DetailsView - Adding Template Field By Code?
Feb 11, 2010I'm trying to add an DropDownList to a DetailsView by code, because i'm writing a solution that let's the user select an table and view your records and edit them, some of theese tables, have a foreign key column and the user must have to select some item in the list.
Below is my sample code:
[Code]....
the code above is working correctly, when the user click in the buttons New or Edit , the DetailsView opens correctly, showing the DropDownlist, but when the user click in the buttons update or insert , an error occurs, the viewState cannot be loaded:
Failed to load viewstate. The control tree which viewstate is being loaded must match the control tree used to save viewstate during the previous request. For example, when controls are added dynamically, the controls added during a post must match the type and position of the controls added during the initial request.

View 1 RepliesForms Data Controls :: DetailsView Dynamically Suppressing Fields / Error 156
Mar 24, 2010I have a working gridView/DetailsView used as a member Lookup.
Some Fields in the Details View have data only some of the time, and when there isn't any, I want to suppress that row of the detail. No Go.
It seems that some of the function available in other controls don't exist so I cannot make the "field and its "header" Visible = "False"
FWIW, The control is nested inside a loginview control.
[Code]....
When I try and put logiin the control the error I get is:

View 4 RepliesForms Data Controls :: Dynamically Generating Update/delete Statements For A DetailsView Control?
Dec 1, 2010In my Admin page, I have a drop down list containing all current user tables in the database. The user chooses one.
My DetailsView below uses that parameter to populate itself with data from that table. The stored procedure used to select the data passes a string to sp_executesql. The string is concatenated from a select statement and the tablename parameter. Can I do something similar for Update/Delete statements? I'm not sure of the best approach, given that I won't know which/how many fields will be in the DetailsView at runtime, and which of these are keys - the choice of table depends on the user. I think Insert will be straightforward - am I right? I would like to streamline things as far as possible. Is it possible to dynamically pass in the values in, say, a string, and get my stored procedure to understand them? And what's the best method of grabbing the values from the DetailsView in this situation?
Forms Data Controls :: Dynamically Adding Rows To A Table
Apr 19, 2010I need to let my user add rows dynamically to a table, and after doing some research, it seems the best way to do this is through a GridView bound to a DataTable. However, I'm really struggling adding dropdownlists to the datatable, and this showing them in the gridview.
Here's the design I want:
ddl1 | ddl2 | ddl3 | ddl4 | ddl5 | ddl6 | ddl7 | textbox
When the user opens the form, he or she will be presented with one row. ddl2 etc will be populated when ddl1 is selected etc etc. When appropriate, the textbox will be enabled allowing the user to enter a comment (this is to report errors, and since users are, at best, not to trust to write the same thing twice, I need to use ddls.
Now comes the question - how do I add a ddl to the datatable? I've tried several ways, but I cannot get them added.

Forms Data Controls :: Dynamically Adding Second HeaderRow To GridView?
Mar 15, 2011I've read a few articles on this, but I keep doing something wrong, and I'm not sure what. I took out all of my customization and just want to add a single header row to the very top of my GridView... Can someone show me how I'm screwing up? This is the code I'm trying to use...
[Code]....
I have tried a few different ways of referring to the GridView table... e.row.parent, gv1.controls[0], etc, but nothing seems to work.
I don't get any errors, just nothing ever shows up when the GridView is rendered. I can't find the code using Firebug to look at the HTML either... what am I doing wrong?
(have also tried using "0" for the rowIndex when creating the new GridViewRow)

Forms Data Controls :: Get Cell Values In A GridView After Dynamically Adding Validation Controls?
Mar 31, 2010So I have a gridview control and I am binding it's datasource dynamically base on a dropdownlist. The gridview contains autogenerated columns with auto generated edit buttons. The datasource binded to the gridview is IQueryable<T> where T will be different for different datasource.
My detail problem is below:
A GridView binded to datasource dynamically with all autogenerated columns. When user click edit link, it will display value in autogenerated textboxes.
When user click update link, I am able to capture the user entered value in the textboxes in RowUpdating event, then pass those values to Linq update function to update the database. Now, the problem begin when I try to dynamically add validation controls to each editing row. In RowDataBound event, I am checking the editrowindex then adding validation control to gridview cell and pointing to cell.controls[0] which is the textbox control when the row is in edit mode, I am dynamically setting the textbox control id so that the validation control can set controltovalidate property. The validation control works, but the updating function is setting everything on the grid to empty string.
I am check the textbox text value in the loop, which returns "" for all cells except the id column. It was returning the correct value before I add the validation control. I guess since I added the validation control on rowdatabound event, will it rerender it's own autogenerated textbox in edit mode so that the text value of textbox no longer available in rowupdating event?
Is there a better or correct way to get the cell textbox value? I am using ((TextBox)dc.Controls[0]).Text where dc is DataControlFieldCell in rowupdating event.

Forms Data Controls :: Adding Spaces In A String Which Is Generated Dynamically In C# Code?
Jul 20, 2010I have a grid. I am building and populating it dynamically in C#. Below mentioned is my issue:
string s1 = "string1";
string s2 = "string2";
And then I have a header cell text which needs to be populated like this.
headercell.text = s1 + new string(' ', 20) + s2;
I am not able to get the extra 20 spaces between s1 and s2. It gives me just one space instead of 20 spaces.
I tried using headercell.text = s1 + s2.padleft(' ', 30); even then I am not able to get more than one space between strings s1 and s2.

Web Forms :: Dynamically Created RequiredFieldValidator Are Always Validating True?
Jan 20, 2010I'm creating several textboxes and dropdown controls. Some have a related RequiredFieldValidator control. The RequiredFieldValidator is created as follows:
[Code]....
This method is called from the following section of code which inserts rows into a table. Insert location is marked with a PlaceHolder control (ID="tblInsertRow").
[Code]....
When the user clicks the "Save" button, I force a validation of all validators as follows:
[Code]....
The problem I'm having is that Page.IsValid is always "true". I read some older posting that stated that you cannot use RequiredFieldValidator with AJAX, but I don't believe that's true anymore since I've done it before with static controls. This is the 1st time I'm trying to do this with controls created at runtime. These controls are created in a User Control that is displayed on a Page with a Master Page.
