Asp.net - Update Telerik ComboBox And RadGrid?
Nov 2, 2011
I have inherited an application that uses telerik controls. This is my first time to work with it and I'm a little confused.I have a RadComboBox that has its values hard coded. When the user selects an item, a RadGrid is refreshed to show the records that correlate with the item the user selects from this combo box. This all works great.I'm trying to create link buttons, so that when the user clicks on one, the RadComboBox value is changed to whatever value I set it to in the codebeind page and the RadGrid is refreshed to show the appropriate records.I can set the value of the RadComboBox, and see what value it has when debugging, but the RadComboBox in the browser does not reflect the change and the RadGrid is not refreshed when I programatically execute the event handler for it.

I have a Telerik Radgrid containing all the valid usernames and passwords that can be used to unlock functionnalities on my web page. The password is encrypted, so you have to click the row to decrypt and show the actual password. All usernames and passwords can be changed by an admin When the admin presses [ENTER] to submit the new username/password combination (instead of pressing the submit button), the new combination is actually submitted (which is fine).

I have a Telerik RadGrid that has three bound columns and one button column. I would like to let the user edit the values in only one of the bound columns. The user can add a new record so i can't set the two bound column to read only. Is there anyway i can do this in the ASPX or do i have to do it in the code behind? I have some code that is working but it is not the best.Here's my code:
Case "Edit"
Dim aoeAnswerCode As GridBoundColumn = CType(e.Item.OwnerTableView.GetColumn("aoeAnswerCode"), GridBoundColumn)
aoeAnswerCode.ReadOnly = True
Case "Update", "PerformInsert"[code].....

I'm basically trying to implement the functionality of the example here ax/grid/examples/dataediting/editondblclick/defaultvb.aspx) on my own site, but instead of using a data source control located in the page markup (like in the example: essionDataSource), I'm using a dataset that I get from some server code-behind. I am able to successfully get my double-clicked row into edit mode with my dropdowns successfully

I'm doing a form to add/edit/delete values from a data catalog. everything goes fine but the Radgrid doesn't update after Submit Button is pressed in the edit/new dialog. i did it before in a more complex form but i can't figure exactly what's wrong.
in the update the data where the new data will be overwritten dissapears after postback. (i have a way to solve this)
mnlib is a library of my authorship to deal with common tasks i know that queries with strings like {$database_name} is not a standart practice, and probably is not recomended, but i have to deal with it . i'm doing almost everything programatically some of the code is ommited because character limit in post Updated: Reduced code, i'm afraid if keep reducing code, i will eventually delete something important to the iusse

I am planning not to use Aspx for this 2) The node named Item would eventually change as per app Requirements. So, I don't want to restrict my xpath to something like "//Product/Item"..[code]I am reading this xml from codebehind and iterating through xmlnodes to display in the grid. Please find my snippet below:Dim root as new xmldocument() ' After loading the above xml into root..[code]I need the Columns: ItemID, ProductNo, indented Description with ManufacDate and ManufacID. I m not sure how to get this displayed.

I have a radgrid bound to a SqlDataSource that includes a hidden, readonly column that stores a pk. I want to pass the value bound to that column to a stored procedure for Updates but the default behavior when the column is readonly is not to pass the parameter to the sqlDataSource. My question is whether there is a way to pass that value without having to go into the code behind. Here is a snippet of my asp markup.
<telerik:RadGrid ID="rgEmployees" runat="server" AutoGenerateColumns="False"
DataSourceID="sdsEmployees" GridLines="None" AllowAutomaticUpdates="true" AllowAutomaticDeletes="true">
[Code]....
If I set readonly="false" on the It works fine but then the user can edit the primary key value which is not desired. I know work arounds in code behind but is there any way to do it straight in the markup?

I have a RadGrid with a filtercontrol on it. The grid fits the size of the window, but certain views have quite a few columns and when the columns get shrunk down, the filter controls don't resize to fit. Is there any way to set those filter controls to auto fix within the width of the column?

I've got a repeater I've bound to column names that are filtered, as they're applied (using sessions currently, I might change this to loop through the columns looking for filters now that I really know how the grid works).
I've got a button next to each filtered column name that is to remove the filter from the RadGrid.

I have a datagrid that is populated using a stored procedure. One of the columns is called LotNum which I would like to have as the combo box....this combo box should be populated by a table called CurrentLotNumbers, with the field LotNumber. My current coding is below. I am using windows forms and vs 2005. What do I need to add so the user can use this combo box, and do I need to add anything extra to my save button which saves the changes to the datagrid.

I am working on a project that uses lots of custom class objects.Before starting work on real project, I tested the object behaviour on a temporary project. And find that if i add the object to a list and combobox and then make any change to the object property then it reflects in list and combobox.But after using the same process in real project the change does not reflect. how can i update object property placed in the combobox.for eg.Class X has property id and name created objX of type Class X and set id=1 and name='All' insert objX to combobox now, in the same form and in other function when i get objX from combobox and change name='None', then it does not reflect in combobox.

I am trying to update my database based on the selected values in two comboboxes.
Combobox1 = Manufacturers
Combobox2 = Orderlists
In the App the user selects a manufacturer and then an orderlist and then presses Ok button which updates the default orderlist for the manufacturer.I am having problems on buttonClick event which updates the data, just unsure of method, if somebody could even point me towards a good tutorial it would be great as I have searched high and low for one.
Code is as follows....

I had a functioning datagridview that was created from VB2010's datasource by clicking on a table, picking datagridview and dragging to a form. I changed three of the columns of the grid to comboboxes bound to different tables. If I change a value in a column (not a combobox column which still shows the value from the original table), I receive InvalidOperationException was unhandled on Me.TableAdapterManager.UpdateAll(Me.MasterDataDataSet). What code do I need to add if I change columns to comboboxes?

I have a telerik radgrid, like shown underneath [code]When I click one of the rows, it will display the password of the clicked row, like so:[code]That works fine. I am proceeding this way because the decryption of the password is a rather complicated and long process, so decrypting one password at a time is less time consuming, especially when the user doesn't need all the passwords.When I have the password displayed, I'd like to be able to select the password in the grid to copy it. Unfortunately, the radgrid will fire the "RowClick" item command once more, and the row gets de-selected. Therefore, I cannot copy the passwords. My question is: Is there a way to cancel the itemcommand of a radgrid under certain circumstances? I'd like to be able to disable the itemcommand event when the password is already decrypted.[code]

I'm receiving a very peculiar Telerik error, I was wondering if any of you with Telerik experience had come across this one before.
I'm using a RadComboBox, when trying to build I get this error :
Method 'Protected Sub
ddlMyDropDown_SelectedIndexChanged(sender
As Object, e As
[code]....
It all runs as expected when I force run the project, but it won't build successfully or allow me to publish. The error message just doesn't make any logical sense.I've tried using System.EventArgs assuming that the Telerik event args derive from it. But still no success.

I go about upgrading the Telerik ASP.NET controls? I am currently using the Q3 2008 release and I just recently bought the Q1 2009 SP1 release. How do I upgrade my projects? Do I need to uninstall the old one and install the new one or just install the new one? Also how do my projects get upgraded? Also, what about my projects that I have "live"? Do I just need to upload the new DLLs and and change my web.config?
