GridView Conditional Button Visibility?

Mar 28, 2011

I have this itemtemplate for a gridview column that is pulling data from a SQL database. My Question is how would I perform a check to see if my field ActivityFile has a value (which means a file is in the db) and then display the LinkButton at which point I generate code to download the file (already done and works).

<ItemTemplate>
<asp:LinkButton ID="DownloadFileBtn" runat="server" visible="false">Download File</asp:LinkButton>
<br />
<a href="<%# Eval("ActivityLink") %>"><asp:Label ID="Label4" runat="server" Text='<%# Bind("ActivityLink") %>'></asp:Label></a>
</ItemTemplate>

Setting Visibility Of Button Control In GridView Header?

Nov 8, 2010

I have a gridview that displays entries from a data table. I am giving users the ability to select a subset of the data in the table by having a textbox and search button in the grid view header. The search button fires the gridview row command, and changes the underlying sqlDataSource's select command, and adds the text value from the text box as a parameter.

Also, I have a "Show All" button in the header, that clears out the select parameters, so all entries in the table are shown. Again, this works perfectly.

What is NOT working is controlling the visibility of the "Show All" button control. Below is the html markup for the data grid header template:

<HeaderTemplate>
<asp:Button ID="btnShowAll" runat="server" CausesValidation="False" CommandName="ShowAll" Text="Show All" />
<asp:Button ID="btnSearch" runat="server" CausesValidation="True" CommandName="Search" Text="Search" ValidationGroup="vldSearch" /><br />
<asp:TextBox ID="txtSearchName" runat="server"></asp:TextBox>
<asp:RequiredFieldValidator ID="vldSearchName" runat="server" ErrorMessage="You have to provide an attorney name to search for." Text="*" ControlToValidate="txtSearchName" ValidationGroup="vldSearch" ForeColor="White"></asp:RequiredFieldValidator>
</HeaderTemplate>

In the Row Command event handler, here is how I am setting the visibility of the button:

If Not Me.dgAttorneys.HeaderRow Is Nothing Then
Dim btnShowAll As Button = Me.dgAttorneys.HeaderRow.FindControl("btnShowAll")
btnShowAll.Visible = Me.sqlAttorneys.SelectParameters.Count > 0
Trace.Write("Show all status is " & btnShowAll.Visible.ToString)
End If

The trace statement is showing the correct visible status - if the "show all" button is clicked, I do a SelectParameters.Clear() on the sqlAttorneys sqlDataSource.

Is my problem due to a misunderstanding of how the "FindControl" method works - I had assumed my new btnShowAll that I define is actually a reference to the "physical" control on the aspx page, so any changes I make to my local object is reflected in the control on the page.

If this is not the case, what is the best way to get a reference to the button control in the header row of the grid view?

AJAX :: Two Update Panels Interfacing With External Button - How To Control Button Visibility

Jun 15, 2010

I have a page with 2 update panels

UpdatePanel1 contains a gridview1 and a standard panel, pnlForms. gridview1 has a linkbutton which is processed in the gridview1_rowcommand

UpdatePanel2 has gridview2.

There is also a Submit button that isn't in either UpdatePanel but may be a candidate to go into its own UpdatePanel. The Submit button is a trigger for both update panels

The behavior I would like is:

1-Initially, all visible except pnlForms and Submit button 2- When linkbutton in UpdatePanel1 gridview1 is clicked, pnlForms and Submit button become visible. 3. When Submit button is clicked, both gridviews should be refreshed, and PnlForms and the Submit button should both become not visible. I believe I may have to put the Submit button in its own UpdatePanel3 but am not sure how to proceed.

In my present code, everything works as desired except Submit button (not presently in any Update panel) is always visible. Assuming Submit button is initialized to not visible, how do I get it to appear when I click the link button in gridview1 and to disappear when it is clicked?

Bind Button Visibility To The Expression (C#)?

May 19, 2010

I have a delete button in each row of GridView (component ASP.NET). I want some of the delete buttons to be invisible. The visibility of the delete button should depend on the data that are back the row.

GridView is backed by EntityDataSource. GridView displays entities called Category, one instance in each row. Entity Category has (besides others) also a field of type EntityCollection. Name of that field is Items. Basically I want to allow user to delete a row only if the Items field of backing Category entity is an empty collection.

This is how the button looks right now:

<asp:Button ID="DeleteButton" runat="server" CommandName="Delete"
Text="Delete"
Visible=??? ></asp:Button>

I don't know what should replace ???. The button schold be visible only when this expression evaluates to true:

((SimpleEShop.Model.Category) dataItem).Items.LongCount() <= 0

where dataItem variable contains data of current row in the table. What is the binding that I need ?

Forms Data Controls :: Formview Button Visibility Not Working Correctly?

Apr 17, 2010

I have a formview that displays user info from a dropdownlist. One account may have many users, but one account Primary. I am trying to disable the Edit/Delete button in the formview if the selected ID is the account primary. The problem I get is this.

Step 1: page_load - the primary user is displayed by default, but the delete button is enabled - not right

Step 2: I use the dropdownlist to select another user (not the primary) - everything's fine

Step 3: I then select the Primary User, the Delete Button is disabled - perfect

Step 4: select another user, delete button still disabled - Not right.

[Code]....

1. As you can see my sqlSelect Parameters are bound to the DropDownList.SelectedValue, but is t seems like my if statement for comparing selecteduser to varAdminID doesn't work except once.

So to help debug, i added a label control that displays the selected userID, but on page load the label is blank. but it displays the first record on the list anyway. so if this is the reason for not disabling the delete button on page load then why later does it not reable the button when the user is not the primary, and the UserID is displayed on the label and it is not the primary userid?

AJAX :: Repeater Button Works Inside The Conditional Update Panel?

Nov 17, 2010

I have two update panels on my page. One of them contains a list of users which is retrieved from the database. When I click a search button (which is outside of the update panel) the users are retrieved from SQL server and displayed in a repeater inside this update panel. Each of the users has a button next to them to 'Edit'. The seconds update panel contains all of the fields for a user. Textboxes, checkboxes and what not.

My plan is to click the search button as you normally would, and then when you click the 'Edit' button on a user, the second update panel fills with their details. This works except that when I do this the first update panel is updated again and because it hasn't searched for any users it goes blank.

So what I did was set both the update panels to conditional, and then call the first panels update at the end of the search code in the search button click event. So that worked, but now the repeater inside the first update panel is not firing the Item_Command event, so I can't get the details for a user. How can I resolve this so that the repeater button works inside the conditional update panel?

Forms Data Controls :: How To Change The Visibility For Update And Edit Button With This Details View

Apr 4, 2010

I have a details view with buttons in the footer. When the user clicks the edit button the calls the ChangeEditMode() method. I want to change the mode of the details view to edit mode which seems to work fine. It goes into edit mode with a text box. I also want it to set the visible property of the edit button to false and set the visible property of the update button to true. Then while still in edit mode the user can click the update button that will call the appropriate method to persist the changes.

I got the changemode() to change to edit but can't change the visible property of the buttons correctly. This is what I have so far. Can some one please tell me what I'm doing wrong?

Control Gridview Visibility Using Javascript?

Jun 19, 2010

I have a gridview and I have to control the visiblitiy of the grid columns using javascript. Consider this gridview. I have a few columns.

<asp:GridView ID="grdTest" runat="server" AutoGenerateColumns="False" Width="100%">
<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:CheckBox ID="chkResource" runat="server" />
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Resource">
<ItemTemplate>
<asp:Label ID="Resource" Text='<%# Bind("Resource") %>' runat="server" />
</ItemTemplate>
</asp:TemplateField>
<asp:BoundField DataField="Description" HeaderText="Resource Description" HtmlEncode="false">
<ItemStyle HorizontalAlign="Center" />
<HeaderStyle HorizontalAlign="Center" />
</asp:BoundField>
</asp:TemplateField>
</Columns>
</asp:GridView>

I can control the visibility of these columns at the server side by using this -

grdTest.Columns[n].Visible = false;

But, I have to control the visibility from the client side using javascript. I tried a lot but I was only able to access either the row object or any particular cell of the gridview.

grid.rows[index].cells[i].style="display: none"; //for cell

Is there a way to access the column object of the gridview and control its visibility using javascript?

Forms Data Controls :: Conditional Formatting In Gridview?

Feb 2, 2011

I have a gridview on my aspx page. I know we can format gridview row in rowdatabound() of gridview. But my problem is bit different.

In my gridview, i have a column customer code, a single code can repeat more than once successively. I want for one customer code, row color should be blue and as soon as code changes colour should be yellow for that code. Similarly when code changes again color should be blue again.

In this way color of my gridview rows should be blue and yellow alternately based on my customer code.I have arranged customer code in order by using sql order by clause.
