How to convert null value into string in c# .net?

由 天涯浪子 提交于 2020-01-26 01:42:12
问题 I am using gridview's default update method in which it allows me to update row in gridview itself by converting cells into textboxes. I want to check validations that if a particular textbox (cell) remains empty or blank then it should not update its value. For that i have written following code: string.IsNullOrEmpty(e.NewValues[0].ToString()) But it gives an error like object reference not set to an instance of an object. May be it can not convert null value of e.Newvalues[0] to string .

Item-Selection with Checkbox in Android-GridView

由 情到浓时终转凉″ 提交于 2020-01-25 09:35:27
问题 I've come to a problem with the Android GridView. I already tried various solutions from Stackoverflow but none of them actually worked. I'm populating a GridView with the help of an ArrayAdapter. The Adapter inflates a layout containing only an image and a checkbox. I'm using that "convertView"-thing in order to prevent flickering when the images get added (nearly 500 images are getting added to the GridView). The Problem : When I check a checkbox and scroll, the checked-state disappears.

由 点点圈 提交于 2020-01-24 21:09:27
问题 Does anybody know a way to remove all the padding from GridViewItem? I'm using very small items (not too small though, I exaggerated in the picture below) and there's some padding when selecting the items which makes it good really bad and I'd like to take it out. This is what I mean: The code for the image is this: <GridView Margin="120,80,0,0" SelectionMode="Multiple"> <GridView.ItemsPanel> <ItemsPanelTemplate> <VirtualizingStackPanel Orientation="Horizontal" /> </ItemsPanelTemplate> <

What is the sequence of events firing off in asp.net Gridview control?

由 廉价感情. 提交于 2020-01-24 04:05:39
问题 I use GridViews pretty often and sometimes I get confused to where to put certain code. What is the sequence that events are fired off including all page events? Edited: I really am also trying to understand what happens between the page and the Gridview. Do the events ever cross? Or do all page events occur at once then all Gridview events occur? And not just GridViews, any control - but mostly page and GridView interaction. 回答1: protected void GridView1_Load(object sender, EventArgs e) {
