my goal is to do this:a user clicks on one row on the datagrid (.net 3.5). (the user can click anywhere of the row)then the form postbacks, and then other content based on the selected row on the page will be updated.
View 5 RepliesI have a DataGrid that has a dropdown list in an ItemTemplate. Basically, users select a value from the dropdown for each row of the datagrid. When the page is posted back, the selected index of the dropdown list is always reset to 0, and the items are re-bound.
Does anyone know why this might happend? The dropdown items are hardcoded, so there is no external data binding that happens on post back.
I have a web application that takes information entered by the user and displays it in a few datagrids, that are located withing a multiview.
In order to enter a row to a datagrid the user enters some information and clicking on a button calls a function that adds the data to an arraylist, which is the source of the datagrid. In addition, every postback the data is binded to the datagrid.
It all works fine in the first time, but from the second row and on it enters only parts of the data and ignores the rest.
I have a DataGrid bound to an ObjectDataSource, as you know once the DataSourceID on DataGrid is set, data binding happen automatically without any coding. But due to requests from end users, I need to prevent the data binding when the page is loaded the first time, i.e. data binding should only happen during PostBack. How do I do that?
View 3 RepliesI have a Datagrid control in my webform, which directly pulls out data from our database.
For each row, I have a custom button at the last column. Its looks like:
[Code]....
What it does is it simply opens a new window with the row information.
The problem is, this button works with 2 clicks, not one click
I need to swap around the rows and I do that with
[Code]....
Obviously I am using the tableDnD() function to do that, but after I swapped them, I am saving the datagrid in a DataTable as it is (altered). However this doesn't happen. I need the changes to be posted back to the server. I tried to __doPostBack() after the onDrop function with no luck.
i have a datagrid that i want to be able to select a row and be able to edit the details of the row selected. Im connected to an sql azure db.
View 1 RepliesI have a datareader that returns a few fields (orderid, customer id, customername, location, total amount - as an example) that is bound to a datagrid on an asp page. The datagrid simply displays customername, location and total amount and has 2 buttons
below it labelled 'Add New' and 'Edit' and I would like the following to happen:
1) when a user clicks on any cell in the datagrid, I want that row to be highlighted in someway so that the user is aware of the highlighted row.
2) If the user then clicks on Edit button, I want to go to another page that displays the details of that order by passing the orderid of that row to the next page.
The idea is that the user selects a row on the datagrid and then clicks edit which will take them to another page where they can edit/updated details but I'm not sure how I can pass a value of a selected row in a datagrid to another page. I am aware that you can add a template column with buttons on but I would like to have one set of buttons rather than have buttons on each row of the datagrid.
I'm needing to get the selected rows, based on checkboxes, to insert into a different table than that that the gridview is formed from. I've created an innerjoin datasource to try and solve this but, still having problems finding something that works. I also need it to insert based upon a button click not inside the gridview as I believe otherwise would only hamper the situation more.
View 7 RepliesWhat I am looking to do is have a page with 2 seperate datagrids on, I want to be able to add the selected rows from DataGrid1 into DataGrid 2 either with a button click or using drag and drop functionality (Im guessing this would require javascript and I have no experience with this language, is it difficult to learn or could I just alter code from elsewhere?). Once the row is added into DataGrid2 I would like to be able to add some information, such as Quantity and DateDue (could this be added in a pop up box when the part is added?) Also I would like fields in DataGrid1 to be based upon a search with several different options that the user specifies, i.e the ability to search based on project number, however it would return eitheer parts or assemblies depending on a check box selected. I have very limited programming knowledge but Im guessing I would be able produce a query based on the inputs, but in order for this to work wouldnt the page to postback everytime an option was changed.

I have a repeater which contains a hidden link button that fires when I click a row in my repeater.
Here is the markup for my repeater:
<div id="divResults" style="height: 290px; overflow-y: auto;">
<asp:Label ID="lblNote" runat="server" Text="Note: select a row to edit."></asp:Label> [code]...
Here is the javascript thats added to each row in the rptLocations_ItemDataBound:
Row.Attributes.Add("onclick",
"javascript:__doPostBack('ctl00$mainContent$rptLocations$ctl0" + (e.Item.ItemIndex + 1).ToString() +
"$lbtn_SelectRow','')");
When I click the repeater row it fires the SetLocationControls method. As you can see my repeater is wrapped in a DIV of height 290px. When the are more than 9 rows in my repeater you have to scroll the div down to view this row. When I click this row it does the postback but doesn't fire the SetLocationControls method. I've had a look in the source it's created the click event to the repeater row like all the other rows. why this method isn't firing on the rows that aren't initially visible in my DIV?
I have four TreeViews bounded to different SiteMaps with custom Provides. When I click on the +(expandCollapse) near the node that appear under the CurrentProvider.CurrentNode of the page- just in the first click, in debug ,I see it's cause to commit the OverrideChildControls that I write and then goes to PageLoad...it's disrupt everything..I want that all the Nodes will be load without Load all the page Did someone had this problem?I will be glud to know the solution..
View 2 RepliesI have a GridView within an UpdatePanel - <asp:UpdatePanel ID="UpdatePanel1" runat="server" ChildrenAsTriggers="true">
Without listing any Triggers, I get a full postback when I visit a particular row within the GridView and click the 'Edit' button for that row.
However, if I enter the following trigger...
<Triggers>
<asp:AsyncPostBackTrigger ControlID="GridView1" EventName="RowEditing" />
</Triggers>
...I get an async postback when I click the 'Edit' button for a particular GridView row. This is what I want. In fact, I also get an async postback if I then click the 'Cancel' button for that GridView row which appears after having clicked the 'Edit' button.
However, if I instead click the 'Update' button that appears after having clicked the 'Edit' button, I get a full postback. I have tried almost every GridView EventName
I can find to add to the <Triggers></Triggers> section to get a click of the 'Update' button to result in an async postback, but with no luck.
What EventName should I use in the <Triggers></Triggers> section to get a GridView to do an async postback when clicking the 'Update' button for a particular row?
I have 2 grids gvParent & gvChild I would like to filter gvChild when a row is selected in gvParent the linking fields are contractNo

View 3 RepliesI find a special circumstances as follows:
My web form contains a postback button. The button will postback and call a server-side method. The method will process something that may spend about 20 seconds. However, user may try to click the button several times within the waiting period. The sequential clicking may cause the first running method incomplete and stop, since the second click postback will dominate the method and start again. How can I solve it?
PS: It can not use client side script to disable the button, because it requires to use some server-side validation within the method.
