Slider not displayed

[John Davis]

Most features work fine but I have some problems with RadGrid for Ajax. 

1. When the page displays intially, the slider does not display. (Even if I set AlwaysVisible="true") However if the user clicks on a row in the grid thenthe slider displays. ASPX is below.
How can we display the slider when the page displays?

2. Do you have an example of a paging "Slider" that has the text horizontally aligned (side by side) with the slider graphic?
e.g. the words "Page: 1 out of 6667 pages" would appear to the right of the slider graphic.

3. Is there a special way to set font-size for data in the grid?  I set it to "smaller" but it stays big.

4. Is there an example or guidance on how to do the following.  Suppose we need a grid to edit employee records.
Each employee is in one company and each employee can be in zero or more departments inside the company.
So if we edit or add a new employee the user must select a company (e.g. from a dropdown list of all companies) and AFTER selecting a company the user may select zero or more departments (e.g. from a listbox).
So a normal edit feature is not sufficient.  The contents of the list of departments depends on the company selected.
I can think of two general ideas. 4.1) If the inline edit form could have an event associated with user selection of a company from ddlistCompany. This event would cause data to be loaded into the listbox for Department that is on the edit form.

4.2) Another idea is not as nice for the user but could work.  We could have a second edit button on the grid for "Edit Department". When the user clicks this button some kind of popup window is displayed that contains a listbox of Departments that are associated with the company in the row containing the edit button the user clicked on.

I found one way to do this.  Have 2 edit form user controls, one for company data and one for department.  You can use CommandArgument in these controls so you can identify them on the page or user control that uses them. For example the following. If CommandArgument == "S") I know which edit form user control should be the "active" one.  The grid will have one edit button associated with each of thes 2 edit form user controls,

protected void RadGrid1_ItemCommand(object source, GridCommandEventArgs e)

{

if (e.CommandName == "RebindGrid")

{

PopulateOnPrerender =

false;

SetLabels();

RadGrid1.DataBind();

}

if (e.CommandName == "InitInsert")

{

if (((LinkButton)e.CommandSource).CommandArgument == "S")

{

RadGrid1.MasterTableView.EditFormSettings.UserControlName =

"~/Controls/UsersControlEditSCS.ascx";

}

else

{

RadGrid1.MasterTableView.EditFormSettings.UserControlName =

"~/Controls/UsersControlEdit.ascx";

}

}

}

Hi John,

Try using AdvanceDataBinding techniques to bind the Grid.

Thank you Princy. I have some ideas now on #4. Any suggestions on items 1 and 2 about the Slider for paging?  Item 1 is a real problem for end users who will not see the Slider.

[Yavor]

Hi John,

If the issue with the slider is persisting at your end, you can open a formal support ticket, and send us a small sample, which we can debug locally. As soon as we do, we will get back to you with more information.

We are having a simular problem.
When a RadGrid is located inside a RadDock and on another RadDock we have a page that contains a RadCombo box the Slider does not display. Remove the RadCombo and the Slider comes back. We just removed the RadCombo and replaced with a DropDownList Box but would love to find out why this happens. (theme is "Simple")

[Tsvetina]

Hello Daniel,

I could not replicate the described problem by only having a RadGrid with a Slider pager inside two RadDocks and having a RadComboBox anywhere on the same page (within and ourside the docks). So, would it be possble that you send us your grid declaration and if possible a live url that we can inspect? Alternatively, you can provide us with a more detailed set of steps that we can use to reproduce the issue.
