I think it is possible, what steps should I go through? And those videos all using Linq as data source, what if I have my own object data source and binding them in code behind, what about it?
View 3 RepliesI've never use these two before. I watch a video on DynamicControl today, mention nothing about implementing the .ascx. so, end up pretty useless.Can someone shed some light on these two controls? or are they just lamb?
View 1 RepliesI want to change the text of gridview empty data template based on diff scenerio's.
View 3 RepliesHello Good Day,
I want to change the ItemTemplate of Repeater based on different queries on my database.
Scenario -
Say for example,
- First query returns EmployeeID, EmployeeName - In this case repeater should display both fields.
- Second query returns EmployeeID, EmployeeDOB, EmployeeMemo - In this case repeater should display all three fields.
However this cant be done if I set hardcore EVAL in the markup. So i need it to be Dynamic.
Possible Solution in my opinion -
I found one way, that is creating a dynamic Template and then assigning its fields during Item_DataBinding.
Question -
Is there any other simple method, other than creating a dynamic Template all from its scratch. Means let me say, I hardcore fields like
EmployeeID, EmployeeName, EmployeeDOB, EmployeeMemo in the MarkUp, but in case of first query it (Repeater) should neglect
EmployeeDOB, EmployeeMemo and in case of second query it should negect EmployeeName.

I have a gridview and basically at page load I want it to display with an empty row. The first field in the gridview would be a template field containing a textbox. I wan't to be able to type in, for example, a product code ('abc'). This would be the parameter for the stored procedure and then the rest of the columns (40+ additional columns) in the gridview would populate with the rest of the data pertaining to that product code (i.e. price, unit of measure, etc.). In short the template field texbox is the control to bind the gridview.
After the row is populated I could click a button or link that would add that entire row to my gridview and then add another empty row where I could enter another product code... populate the row then add that row to the gridview. and so on...

Vendor Name 20 Points 50 Points 75 Points
ABC 5 7 8
XYZ 10 16 5
First Question, How can I represent the data in the above way?Second Question, If I add one more point like 100 Points, then how the one more column will come like below:
Vendor Name 20 Points 50 Points 75 Points 100 Points
ABC 5 7 8

XYZ 10 16 5

I'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.

I need to get access to the page index of the gridview so I can correctly get some data from a coresponding array to set the cell's contol properties correctly. Below is what I've got so far. The ExcelObject is a class that houses both the data read in from an sutomer submitted excel file and a matching 2 dimensional array of characteristics that I use in this case to set the CssClass property. My problem is that when I enable paging for the gridview I don't get the proper datasource row index when the data is read by the databinder.eval; what I'm getting is the current row of the gridview being generated.

I there I have recently created an ASP website wich uses .net 4 and SQL db but soem some reason even displaying 20 records in a gridview is slow... So after some reading I converted the website to a Web Application Project so its compile prior to publish.. But yet again this is a bit slow. pages loading time is not of a bit issue...

View 3 RepliesI have a formview with various templates set up for a database that has 255 columns. I need the insertitemtemplate to pre-fill values based upon a specific selection by the user (just like the edit item template) but when the template is switched to insertitemtemplate every text box is cleared. The idea is that a new entry is usually made by making minor changes to an existing entry. With 255 fields I don't want to require the user to enter every field when only three or four need to change.
View 8 RepliesI have a gridview which the columns are created programmatically.
When a button is click i will clear all columns and add the columns that I want. Im adding a boundfield which is not a problem. When I add a template field, I must add also the item template which is my problem.
How can I add a item template in the template field I created which is binded in my datasource. Also what event handler should I use to do this.
Here's the part of my code:
[Code]....
Someone know how can I bind a label item template from the datasource. The label item template should be firstname + middlename + lastname.
If im not doing it programatically, it will be just concatenating eval(). But how can create item template and bind it programmatically?
Setting up the editItem template of a gridview. I have a template field with a dropdown list for editing. When the gridview goes into edit mode the dropdown list is displayed with all the right options but the current value of the field (pre-editing) is not the selected value of the dropdown list? How do I make that happen? I have a couple fields where the editItem template will use a dropdown list and I'm sure a user will not realize those values have changed and they will just edit what they intended to edit and save the changes, inadvertently also making changes to other fields.

View 1 RepliesI'm trying to implement a custom filter template for all text based searches and running into problems constructing the query. I've been following the instructions posted on this blog but not sure how change the GetQueryable method to perform a WHERE columnAttribute LIKE '%something%'query. In the example on the blog the expression is an equality which works if the text I enter exactly matches the text in the database column.
At the moment I'm using the new QueryExtender feature along with the SearchExpression control but this requires creating several custom pages for all the tables I need text search functionality for. I would like to DRY this up by creating the custom filter template.
Have spent hours trying to create a Dynamic Data Field Template holding a DropDownList which is extended by the AJAX Cascading DropDown extension.Final form holds multiple cascading dropdown boxes. User selects Country (Land) then Postcodes, Counties (Provincie) are populated. Once postcode is selected then towns (Plaats) are populated. The problem I am now facing is that the viewstate for the dropdown lists is not being saved/restored after an insert action or custom validation error. So basically the dropdown lists are being reset to their default values.Some code (if missing parts, just ask and I will post them) - Don't mind the code structures etc... needs some refactoring :)Attribute I created:
