how to asp.net update panel use in Tree view and grid view


stored procedure is not getting invoked on update command of grid view

  

Hello everybody!

In my project I am using a grid view to display data from multiple tables and I want to update that data on clicking edit button.

For selecting data I am using custom select statement, but for updating I have created a stored procedure which should update two different tables.

 

But when I click on update , it's not executing the stored procedure.

 

here is the code snippet of sqldatasource:-

<asp:SqlDataSource ID="SqlDataSource1" runat="server"  UpdateCommand="editEmployeeInfo" UpdateCommandType="StoredProcedure">

                <UpdateParameters>

                    <asp:Parameter Name="empId" Type="Int32" />

                    <asp:Parameter Name="name" Type="String" />

                    <asp:Parameter Name="address1" Type="String" />

                    <asp:Parameter Name="address2" Type="String" />

                    <asp:Parameter Name="telNo" Type="String" />

Custom Control Design view error

  

Hi

I have created a custom control from scratch and it works fine as in you can build the project that uses it and it works fine at runtime. Problem is when you go to design view the control shows an error in the place of where the control should be rendered.

Error: '<SomeValue>' Could not be set to '<SomeProperty>'


This shows up on all my custom set properties. These properties are created as basic as possible. I can give the properties values in Source view and run the app just fine. I can even add a Onclick event. If I don't set any custom properties the control will render fine in Design view. It's only when I set a value to a custom property.


Property Code Example:

public string Text
        {
            get
            {
                string ret = "";
                object obj = ViewState["Text"];
                if (obj != null)
                {
                    ret = obj.ToString();
                }
                return ret;
            }
            set
            {
                ViewState["Text"] = value;
            }
        }


I've even removed the Category and Description tags with no difference.

I don't know if what I said makes sens, but I hope it

ASP.NET Grid View Paging and GridDataRowBound Problem -

  

Hi,

I have a problem displaying data in a Grid View control when I set a row to visible = false when a certain condition is true.

For example, if a DataRowData value has a condition set to true (custom in table) I set the visible property to false, so the data row will not be visible at run time.

The problem is that I'm using paging (10 rows per page) and if 8 of those rows fall into the true condition that won't show the row, that grid view page will only show two rows of data in page 1. The worst scenario is that if I go to page 2 of the grid view and all the rows (10) fall into the true condition, that grid view page will not show any data at all.

How can I show 10 rows of data at all times in a gridview? In other words, I would like to just show the visible rows at all times.

Any help will be greatly appreciated.

Eduardo.


Change grid view from table to other HTML layout

  

Hi,

You'll have to excuse my ignorance, I'm coming at this from a front-end perspective, and don't really know how to deal with data views in ASP.NET.

Basically, I'm trying to change the layout of some repeated data from a straight table, to something more design-heavy.  It's the same data, just re-organised slightly.  The current ASP.NET code looks like this:

		<table>
			<tr>
				<td>
                    <asp:GridView ID="GVMoments" runat="server" AllowPaging="True" AllowSorting="True"
                        AutoGenerateColumns="False" PageSize="20" RowHeaderColumn="FirstName"
                        SkinID="GroupSkin" DataKeyNames="moment_id" 
                        DataSourceID="SqlDataEditMoments">
                        <PagerSettings Mode="NumericFirstLast" PageButtonCount="20" Position="TopAndBottom" />
                        <RowStyle />
                            <Columns>
                                <asp:BoundField DataField="moment_id" HeaderText="moment_id" ReadOnly="True" SortExpression="moment_id"
                                    Visible="False" In

Very strange error reported in View (Might be a bug in VS2k8?)

  

Hi,

As I say in the title of my post this "may" be a bug in VS2k8 Pro, I have seen these strange little things happen before but whenever you utter the word "bug" people tend to get defensive, so I say it "may" be ;)

Basically I have two List(Of MyOwnClass) and I am going to enumerate through these lists on my view.

I add the Import statement to the top of my view so that my custom class can be used on it.

I add a very simple loop,

                    <%For Each CPDCourse As Download In CType(ViewData("CPDAvailable"), List(Of Download))%>
                    <tr>
                        <td style="width:100%">
                            <a href="<%=CPDCourse.URL%>">
                                <%=CPDCourse.Title%>
                            </a>
                        </td>
                        <td>
                            <a href="<%=CPDCourse.URL%>">
                                <img style="border:none;" alt="View Image" src="../../Content/Images/digitaltraining/view.jpg" />
                            </a>
                        </td>
                    </tr>
                    <%Next%>
