I'm having a problem getting the GridView.AutoGenerateEditButton property to do anything for me. Right now, I set it to true, and I don't even get the button added to my GridView, so obviously I can't even get any further to code the actual events. Here is what I have so far (sorry for the messy code; I'm getting close to my deadline and it's been a bit frantic):
[code]....
Now, the columns are being added exactly the way that I want, and the data is populating properly. However, I don't have the edit buttons that I assume I should have by setting the GridView.AutoGenerateEditButton property to true.
I have a databound gridview using datatable as datasource. Template fields are used to edit the row content.This cell value should get updated in the datatable on text_changed event without using gridView edit. Is it possible to overload the GridViewEditEventHandler for this purpose.
What I want to achieve is that by changing the assignment in the Page_Load method I can hide / show the Edit button, but that does not work. When playing around in the markup file I can make the button show up or hide, but I can never change it from the code behind file.
I also tried to explicitly call dvwSomeDetailsView.DataBind after setting the property, but this also didn't work. Overriding OnPreRender and placing the code from the Page_Load method in their didn't do anything to improve this either.
Maybe I'm thinking too complicated - shouldn't there be an easy way to set programmatically whether the button should / shouldn't show?
when I click 'edit' I can edit rows in the the grid view but when I click 'update' nothing happens - I can still see the 'update' and 'cancel' buttons and it looks like the changes are kept but the database is not realy being updated. The Javascript is running but nothing happens. Doesn't even look the the 'RowUpdated' event is in effect.here is my code:
In page1 on clicking template field named Edit the record goes into detailsveiw (Edit mode) to next page.
In detailsview, I have already set True to AutoGenerateEditButton so that the user update record and Click UPDATE or CANCEL.
I want to show a message "Record Updated Successfully" on clicking update and the page redirects to the Page1 and refresh the page1 with the updated record.
i am working in asp.net and c# i have a grid view. i have 10 columns in that grid view. I have some problems with grid view header text color.some of the columns header have link (for sorting). the color of such header text is a light blue.after clicking the blue color change to another color.
some of columns header does not have link. the color of such header text is gray. i want to make the color of entire header text to single color like gray. after clicking the link it must be in same color.
I have a panel control in gridview's template. I need to hide/unhide panel in javascript function, for that i need to pass panel's id to the javascript. The problem is that all panels have the same id in gridview, so I need to set unique id to each panel.
I tried to do:
<asp:Panel id= "Panel_<%# Eval("ID")%>" and some other variations but always get an error.
The panel contains some other controls, I need it to be server side because I need to set at code-behind (after checking if user is authenticated) What can I do? p.s. It doesn't have to be Panel, any other control that I can find with Findcontrol and can hold other controls.
Update:
I set the the js event in code behind: protected void gvw_RowCreated(object sender, GridViewRowEventArgs e) { if (e.Row.RowType == DataControlRowType.DataRow) { if (UserIsAuthenticated) { HyperLink title = e.Row.FindControl("lnkTitle") as HyperLink; Panel panel = e.Row.FindControl("panel") as Panel; title.Attributes.Add("onmouseover", "ShowHidePanel(" + panel.ClientID +")"); //All get the same id!!! } } }
On the RowDataBound event of a gridview I am setting the name of the HtmlInputRadioButton inside the GridViewRow. The problem is that asp.net automatically makes the name unique therefore ungrouping the radio buttons.
Is there a way that I disable this?
Edit - Here's how I am setting the name:
[code]....
Due to the numbers "106" and "107" in the name of the respective radiobuttons it ungroups them.
is it possible to set a maximum length in my field in gridview?
Below is my gridview sample that retrieve a formatted html in my database..All i want to achieve is to limit the maximum length of characters i.e "50" then automatically create a pagination for the succeeding characters..to be posted in the gridview
There is a small advancement in my app, developing using ASP.Net and C# on fx4.0. Requirement is that my client needs dynamic paging size. He wants to set page size of all gridviews approx 10-15 , as needed. If he wants 5 then my app will display 5 and if he sets 10 then the app will display 10.
I need to perform some string manipulation to a columns contents in a GridView, and I'm using the DataBinding event for the template field for this. I'm converting all Environment.NewLine's to 's for outputting.
Here is the code:
[Code]....
It writes the correct, newly modified, string at the top - but why isn't it feeding back to the grid view?
what I am trying to do is add a method to my gridview's sorting event to add a class to the column being sorted so the user can know if the data is being sorted ascending or descending and on what column. I am currently trying to do it through a switch statement on the sort expression to determine what column it's coming from but I am unaware of how to set the css class.
I have a gridview, and I was trying to use SQLAdapter for the first time. I have it set up but I want the user to enter a Date in the last field of the Gridview and be able to update it. I was looking up examples, and I cannot get it to properly update. The field I want to be able to update is the "TADateUpdate" I have gotten it to show the texbox fields to edit, but I can't figure out a method to update properly.
I have a gridview with a bound column,a template field with an editable textbox and a template field with a readonly textbox.
The bound field value is coming from database. I will enter a value to the editable textbox field. I want to set a value to the third cell based on the entered value in second cell . If the second cell is lost focus i want to set the value to third cell . If the solution is with a javascript function i will be very happy.
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?
I have a GridView with one checkbox and some fields. Now what I want is to set this checkbox dynamically on the execution of a particular function.
ie..i have a mailsend function in my code.. when this function executes the checkbox in my gridview should be set dynamically.. How do I go about acheiving this?
...where [HERE] is the placeholder for my value, from my code behind in ASP.NET before the page is rendered. I generate a guid, and I need that apart of the script on the page.
however everytime i reload the page,backcolor disappears.If i move it out from IsPostBack block ,it works fine but i want to load grid only when the page loads for first time(inside !Page.IsPostBack).
I've been reading the posts here and I'm not finding, or maybe just not understanding, the answer I need so here's my problem.
I have a small gridview and the update works very well. The issue is I need to have one of the fields set to a value from my code either when the record is open for undating or when the update runs.
Is tehre anyway to set the HeaderText dynamically on a gridview? I'm trying the below, it kind of works, but the problem is on the initial load nothing shows up, but when I postback then the new text populates: grdvMyTest.HeaderRow.Cells[5].Text = GetTheCalculatedDate();
I've tried that in both Page_Load and grdMyTest_Load, but same thing happens in both. When the page initial loads the column header text is blank, when I click something causing a postback it pops up. I don't have a IsPostBack check around that line, so it should be running regradless. I'm guessing I'm doing it at the wrong event, either too eariler or too late.
