Batch Edit InPlace , Update All, ExtractValuesFromItem and SavedOldValues giving null

I am working on a grid that puts all the rows (about 8 usually) into edit mode for batch updates.
I have a command button in the command header of the grid to save all the data.

I was trying to use the ExtractValuesFromItem and SavedOldValues collections to perform the update and neither collection has any data. All the entries are there but are all NULL. I don't understand why. I have used this method before in a slightly different situation.
The one thing I can see that is different is in the current grid that this isn't working for I have defined an ItemTemplate and an EditItemTemplate. I am using InPlace edit mode.

I have found that I can get the current values by using editedItem.FindControl("...")... but this is a little more work and it doesn't give me the previous values either.

Should I be able to use the ExtractValues and SavedOldvalues methods in this instance or is there some reason why it cannot be used? If it should be working - any thought on why both collections are coming up with nulls for everying?

The codebehind for updates:

protected void UpdateAll_Clicked(object sender, EventArgs e)

{

try

{

WeatherForecast w = new WeatherForecast();

WeatherForecast orig_w = new WeatherForecast();

foreach (GridDataItem item in RadGrid1.EditItems)

{

GridEditableItem editedItem = (item.OwnerTableView.EditMode == GridEditMode.InPlace) ? item : (GridEditableItem)item.EditFormItem;

Hashtable newValues = new Hashtable();

//The GridTableView will fill the values from all editable columns in the hash

RadGrid1.MasterTableView.ExtractValuesFromItem(newValues, editedItem);

newValues["Temp"] = (editedItem.FindControl("txtTemp") as TextBox).Text;

newValues["Temp2"] = (editedItem.FindControl("txtTemp2") as TextBox).Text;

newValues["ShortText"] = (editedItem.FindControl("txtShortText") as TextBox).Text;

newValues["Pop"] = (editedItem.FindControl("txtPop") as TextBox).Text;

newValues["Manual"] = (editedItem.FindControl("radioManualEdit") as RadioButton).Checked;

newValues["ConditionId"] = (editedItem.FindControl("listWeather") as RadComboBox).SelectedItem.Value;

newValues["UvIndex"] = (editedItem.FindControl("listUvIndex") as DropDownList).SelectedItem.Value;

w.Id = Convert.ToInt32(editedItem.GetDataKeyValue("Id"));

w.Temp = Convert.ToInt32(newValues["Temp"]);

w.Temp2 = Convert.ToInt32(newValues["Temp2"]);

w.ConditionId = Convert.ToInt32(newValues["ConditionId"]);

w.ShortText = Convert.ToString(newValues["ShortText"]);

if (string.IsNullOrEmpty(Convert.ToString(newValues["Pop"])))

{

w.Pop = null;

}

else

{

w.Pop = Convert.ToInt32(newValues["Pop"]);

}

w.Manual = Convert.ToBoolean(newValues["Manual"]);

w.UvIndex = Convert.ToInt32(newValues["UvIndex"]);

w.UvText = WeatherForecast.GetUvText(w.UvIndex);

// TODO: implement day of week editing

// w.DayOfWeek = Convert.ToString(newValues["DayOfWeek"]);

orig_w.Id = w.Id;

orig_w.Temp = Convert.ToInt32(editedItem.SavedOldValues["Temp"]);

orig_w.Temp2 = Convert.ToInt32(editedItem.SavedOldValues["Temp2"]);

orig_w.ConditionId = Convert.ToInt32(editedItem.SavedOldValues["ConditionId"]);

orig_w.ShortText = Convert.ToString(editedItem.SavedOldValues["ShortText"]);

if (string.IsNullOrEmpty(Convert.ToString(editedItem.SavedOldValues["Pop"])))

{

orig_w.Pop = null;

}

else

{

orig_w.Pop = Convert.ToInt32(editedItem.SavedOldValues["Pop"]);

}

orig_w.Manual = Convert.ToBoolean(editedItem.SavedOldValues["Manual"]);

// wDAO.UpdateWeather(w, orig_w);

editedItem.Edit = false;

}

RadComboBox in updatepanel stop functioning after async postback

Hello,

I have a updatepanel containing a list of items based on a datasource.
the list container is a ordinary div, called listingpanel.
I have a combobox in a different div which is invisible when source is selected and saved with the combobox.

I also have a radcontextmenu with a edit button in order to bring the panel to change source in the combobox to the front.
Called "editpanel", a ordinary div.

By default the editpanel is visible and everything works fine.
When using the radcontextmenu to bring the editpanel to the front, a partial postback is triggered, editpanel is displayed but the radcombobox is not functioning, I can see the first item displayed in the list but I'm unable to change it, it wont drop and there is no hover in the combobox when i point my mouse at it, which it is by default.

If I remove the display: none on the editpanel with firebug it works, so I know there must be something with the partial postback.
in the partial postback, all the items are being rebound in the page_init method.

Any ideas ?

Thanks in advance,

Lars

Conditional Sort Expression

I have a column on a grid that can contain data from one of two fields depending on some condition. This condition is evaluated on a row by row basis, so one row can have data from one field, and the next field can have data from another field.

The pseudo logic looks like this:

if (record is user created)
field = date created
else
field = date assigned

How should I set the sort expression on this column?

Template Column with GridDataItem

Hi all,

During the OnItemDataBound, I'm using the GridDataItem to retrieve values from the grid. I'm able to do this without the regular columns. The instructions for the Template column said: For template columns you must find the control in the grid cell and extract its value.please give an example.

Following is the aspx code for the column :
<telerik: GridTemplateColumn HeaderText="Unloading Type" UniqueName="UnloadTypeColumn">
                        <ItemTemplate>
                                     <%#DataBinder.Eval(Container.Dataitem, "_UnloadTypeName")%>
                        </ItemTemplate>
</telerik:GridTemplateColumn>

Thanks in advance.

RadUpload in a grid in UpdatePanel

Hi,

We are trying to resolve a problem from two days now : We are unable to upload files in the RadGrid from a RadUpload.
We found some resolution sample on your forum but none of them could work on our solution because of the UpdatePanel.

Some explanation of the structure of our application :

UpdatePanel containing multiple WebControls => our RadGrid is in one of them.

We couldn't change now the structure of this application : We couldn't remove the UpdatePanel

I took out the code making us crazy, to put it in a project sample with to retrieve the error.

<asp:Content ID="__functionLeft" ContentPlaceHolderID="MainContent" runat="Server">

<asp:UpdatePanel ID="__upDatePanel" runat="server">

<ContentTemplate>

<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">

// <![CDATA[

//On insert and update buttons click temporarily disables ajax to perform upload actions

function conditionalPostback(sender, eventArgs) {

var theRegexp = new RegExp("\.UpdateButton$|\.PerformInsertButton$", "ig");

if (eventArgs.get_eventTarget().match(theRegexp)) {

var upload = $find(window['UploadId']);

//AJAX is disabled only if file is selected for upload

if (upload.getFileInputs()[0].value != "") {

eventArgs.set_enableAjax(false);

}

function validateRadUpload(source, e) {

e.IsValid = false;

var upload = $find(source.parentNode.getElementsByTagName('div')[0].id);

var inputs = upload.getFileInputs();

for (var i = 0; i < inputs.length; i++) {

//check for empty string or invalid extension

if (inputs[i].value != "" && upload.isExtensionValid(inputs[i].value)) {

e.IsValid = true;

break;

Subgrid not populating with data

I have a rad grid, which returns a list of data. I have a subgrid, which should return details in another grid based on the id of the record in the master table and the value of a item selected in a dropdown list. The subgrid passes 2 parameters to a SQL server stored proc.

If I run the subgrid outside of the hierarchical grid the data is returned no problems. I followed the example in the demo and have a label that evaluates a datakey. If I make the label visible the Id displays properly. However the grid below does not show any data.

Any help would be greatly appreciated.

Show ContextMenu from JavaScript

Hello,

I am looking for some code snippet, that will enable the ContextMenu of my TreeView to show. I tried following, but I think it wants some parameter to be passed along with show(parameter); and I do not know what to pass here. I have tried passing in the node, but that did not work.

function ShowContextMenu() {
var tree = $find('tvEstimate');
var node = tree.get_selectedNode();
if (node) {
var menu = node.get_contextMenu();
menu.show();
}
}

The above code gets triggerd by clicking a button, I have also debugged the above code, and there are valid values in each object - tree, node and menu. They all have proper values in them, but menu.show() does not show the context menu. Any suggestion?

Thanks.
