Support ID:664435 -- Loading grid data on demand

Hello,

We had created a support ticket - 664435.

We have posted this,

Currently, we need Telerik grid to allow data loding on demand. i.e we have huge data set that we are trying to assign to grid but then we get 'MaxJSONLength' error. The telerik grid allows to do custom paging by setting VirtualItemCount but then the data fetching has to be handled by the user. Also, the sorting and filtering can not work as we bind only current page data to the grid. We need support so that we can bind data on demand to the telerik grid and it should be able to work with sorting and filtering.

We got reply as below,

Currently the RadGrid provides virtual scrolling mechanism which could properly work with paging and sorting and not a clean built in load on demand. See the online demo below for more information on this matter:
http://demos.telerik.com/aspnet-ajax/grid/examples/client/virtualscrollpaging/defaultcs.aspx

But if you check above link, sorting is working on just current page's data and not on Entire dataset. So is it possible that sorting and filtering work for entire data, along with facility of loading grid data on demand?

Causing the entire text to in the control to jump up and down like a Jack Russell Terrier.

Any help is greatly appreciated.

[Solved] Control's Visible property is set to false if it is added to a RadAjaxManagerProxy

Hello,

I have created few custom controls and have added it to the RadAjaxManagerProxy control. We implement some logic when the control's visible property is set. What I noticed is after adding my control 'txtFirstName' to the RadAjaxManagerProxy, the visible property is set to 'false'. This is causing some undesired actions in our app. The visible property is not set by the code. I have attached the stacktrace for reference. Please assist.

<telerik:RadAjaxManagerProxy ID="AjaxManagerProxy1" runat="server">
    <AjaxSettings>
        <telerik:AjaxSetting AjaxControlID="btnSubmit">
            <UpdatedControls>
                <telerik:AjaxUpdatedControl ControlID="txtFirstName" />
            </UpdatedControls>
        </telerik:AjaxSetting>
    </AjaxSettings>
</telerik:RadAjaxManagerProxy>

Thanks

I have a RadGrid with a NestedViewTemplate shoving more details of the item as in this demo:
http://demos.telerik.com/aspnet-ajax/grid/examples/hierarchy/nestedviewtemplatedeclarativerelations/defaultcs.aspx

I would like to extend this with the possibility to update the item and insert new item. Is this possible?

GridTemplateColumn not working in IE10

Hey Guys,

I have a RadGrid with a few Template Columns that is basically doing the same as the ButtonColumn, but I prefer to use the TemplateColumn type. When I click on the button inside this column, everything works as it should BUT NOT IN INTERNET EXPLORER 10. The error IE10 throws is this:

SCRIPT5022: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled.
Details: Error parsing near '

<!DOCTYPE html>'.

When I switch my browser mode to Internet Explorer 9 (or earlier), then it works 100%. The problem is, we're using Telerik 2012.3.1308.40 and my client is using Internet Explorer 10, on Windows 8 (same as me). It is VITAL that the controls works in IE10. Any suggestions on why this error is happening?

The Grid layout:

<telerik:RadGrid ID="RadGridPolicies" runat="server" AllowSorting="true" DataSourceID="sqlPolicies" EnableEmbeddedSkins="false" Skin="DimsRed" OnItemCommand="RadGridPolicies_ItemCommand" OnItemDataBound="RadGridPolicies_ItemDataBound">

<ClientSettings EnableRowHoverStyle="true"></ClientSettings>

<MasterTableView AutoGenerateColumns="false" CellSpacing="-1" AllowPaging="false" DataKeyNames="groupID, groupName, groupIsActive" DataSourceID="sqlPolicies">

<Columns>

<telerik:GridBoundColumn DataField="groupID" HeaderText="groupID" UniqueName="groupID" SortExpression="groupID" Visible="false"></telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="groupName" HeaderText="Group Name" UniqueName="groupName" SortExpression="groupName"></telerik:GridBoundColumn>

<telerik:GridTemplateColumn HeaderText="Status">

<HeaderStyle Width="20px" HorizontalAlign="Center" />

<ItemStyle Width="20px" HorizontalAlign="Center" />

<ItemTemplate>

<asp:ImageButton ID="imgStatusGroup" runat="server" ImageUrl="Images/imgNoCancel.png" CommandName="StatusGroup" />

</ItemTemplate>

</telerik:GridTemplateColumn>

<telerik:GridTemplateColumn HeaderText="Configure">

<HeaderStyle Width="20px" HorizontalAlign="Center" />

<ItemStyle Width="20px" HorizontalAlign="Center" />

<ItemTemplate>

<asp:ImageButton ID="imgConfigureGroup" runat="server" ImageUrl="Images/imgConfigure.png" CommandName="ConfigureGroup" />

</ItemTemplate>

</telerik:GridTemplateColumn>

<telerik:GridTemplateColumn HeaderText="Edit">

<HeaderStyle Width="20px" HorizontalAlign="Center" />

<ItemStyle Width="20px" HorizontalAlign="Center" />

<ItemTemplate>

<asp:ImageButton ID="imgEditGroup" runat="server" ImageUrl="Images/imgEdit.png" CommandName="EditGroup" OnClientClick="OpenPopup('ModalWindow');" />

</ItemTemplate>

</telerik:GridTemplateColumn>

<telerik:GridTemplateColumn HeaderText="Purge">

<HeaderStyle Width="20px" HorizontalAlign="Center" />

<ItemStyle Width="20px" HorizontalAlign="Center" />

<ItemTemplate>

<asp:ImageButton ID="imgPurgeGroup" runat="server" ImageUrl="Images/imgDelete.png" CommandName="DeleteGroup" />

</ItemTemplate>

</telerik:GridTemplateColumn>

</Columns>

</MasterTableView>

</telerik:RadGrid>

The code behind:

protected void RadGridPolicies_ItemCommand(object sender, GridCommandEventArgs e)

{

if (e.CommandName == "StatusGroup")

{

int groupID = NecHelper.ParseInteger(e.Item.OwnerTableView.DataKeyValues[e.Item.ItemIndex]["groupID"].ToString());

bool isActive = NecHelper.ParseBoolean(e.Item.OwnerTableView.DataKeyValues[e.Item.ItemIndex]["groupIsActive"].ToString());

if (isActive)

taPermissionGroups.UpdateGroupStatus(false, groupID);

else

taPermissionGroups.UpdateGroupStatus(true, groupID);

RadGridPolicies.Rebind();

}

if (e.CommandName == "ConfigureGroup")

{

btnCreatePolicy.Style.Add("display", "none");

hfCurrentPolicyID.Value = e.Item.OwnerTableView.DataKeyValues[e.Item.ItemIndex]["groupID"].ToString();

lblActivePolicy.Style.Remove("display");

lblActivePolicy.Text = e.Item.OwnerTableView.DataKeyValues[e.Item.ItemIndex]["groupName"].ToString();

btnUpdatePolicy.Style.Remove("display");

btnCancelPolicyEdit.Style.Remove("display");

treeViewActive.Nodes.Clear();

treeViewInactive.Nodes.Clear();

PopulateViews(NecHelper.ParseInteger(hfCurrentPolicyID.Value));

}

if (e.CommandName == "EditGroup")

{

string groupID = e.Item.OwnerTableView.DataKeyValues[e.Item.ItemIndex]["groupID"].ToString();

litModalTitle.Text = "Edit Permission Group";

taPermissionGroups.FillByGroupID(ds.AccessPermissionGroups, NecHelper.ParseInteger(groupID));

DataRow dr = ds.AccessPermissionGroups.Rows[0];

txtGroupName.Text = dr["groupName"].ToString();

txtGroupDescription.Text = dr["groupDescription"].ToString();

}

if (e.CommandName == "PurgeGroup")

{

int groupID = NecHelper.ParseInteger(e.Item.OwnerTableView.DataKeyValues[e.Item.ItemIndex]["groupID"].ToString());

taPermissionGroups.PurgeGroup(true, groupID);

RadGridPolicies.Rebind();

}

protected void RadGridPolicies_ItemDataBound(object sender, GridItemEventArgs e)

{

if (e.Item.ItemType == GridItemType.Item || e.Item.ItemType == GridItemType.AlternatingItem)

{

ImageButton imgStatusGroup = (ImageButton)e.Item.FindControl("imgStatusGroup");

bool isActive = NecHelper.ParseBoolean(e.Item.OwnerTableView.DataKeyValues[e.Item.ItemIndex]["groupIsActive"].ToString());

if (isActive)

imgStatusGroup.ImageUrl = "Images/imgYesOK.png";
